Organic Compounds are compounds made of 1 or more carbon atoms covalently bonded together that also contain covalently bonded H atoms.
Correct Answer
A. True
Explanation
Organic compounds are indeed compounds made of one or more carbon atoms covalently bonded together. Additionally, these compounds also contain covalently bonded hydrogen atoms. This definition of organic compounds is widely accepted in the field of chemistry. Therefore, the statement "Organic Compounds are compounds made of 1 or more carbon atoms covalently bonded together that also contain covalently bonded H atoms" is true.
2.
A covalent bond is?
Correct Answer
C. Sharing electrons between two bonded atoms
Explanation
A covalent bond is formed when two atoms share electrons. In this type of bond, the electrons are not transferred from one atom to another, but rather they are shared between the two bonded atoms. This sharing of electrons creates a strong bond that holds the atoms together. Covalent bonds are commonly found in molecules and compounds, such as carbon-carbon bonds in organic compounds. They can also occur between different types of atoms, not just carbon atoms.
3.
A covalent bond can also contain?
Correct Answer
D. Heteroatoms
Explanation
A covalent bond can also contain heteroatoms. Heteroatoms are atoms that are different from the main atoms in a molecule. In a covalent bond, atoms share electrons to form a stable molecule. When a heteroatom is present, it means that there is at least one atom in the molecule that is different from the main atoms. This can introduce different chemical properties and reactivity to the molecule. Therefore, heteroatoms can be present in a covalent bond along with homoatoms (atoms of the same element).
4.
Select all Heteroatoms: (only ones used for the purpose of this course)
Correct Answer(s)
A. Nitrogen N
B. Oxygen O
E. pHospHorus P
G. Sulfur S
H. Fluorine F
J. Chlorine Cl
K. Iodine I
L. Bromine Br
Explanation
The correct answer includes all the elements that are considered heteroatoms. Heteroatoms are atoms other than carbon and hydrogen that are present in a molecule. In this case, the elements nitrogen (N), oxygen (O), phosphorus (P), sulfur (S), fluorine (F), chlorine (Cl), iodine (I), and bromine (Br) are all heteroatoms. These elements have different properties and can form bonds with carbon and hydrogen to create a wide variety of organic compounds.
5.
Presence of Heteroatoms in covalent bonds modifies?
Correct Answer
A. pHysical & Chemical properties
Explanation
The presence of heteroatoms in covalent bonds modifies the physical and chemical properties of the compound. Heteroatoms, such as oxygen, nitrogen, or sulfur, have different electronegativities compared to carbon. This leads to an uneven distribution of electron density in the molecule, resulting in polarity. The presence of heteroatoms can also affect the charge distribution within the molecule, leading to the formation of positive or negative charges. These modifications in physical and chemical properties, polarity, and charge distribution can significantly impact the reactivity, solubility, boiling point, and other characteristics of the compound.
6.
Carbon always forms ___ bonds.
Correct Answer
B. 4
Explanation
Carbon always forms 4 bonds because it has 4 valence electrons in its outermost energy level. In order to achieve a stable electron configuration, carbon needs to share these electrons with other atoms. Each bond represents the sharing of one electron, so carbon can form a maximum of 4 bonds. This allows carbon to create a wide variety of stable compounds, including organic molecules essential for life.
7.
Hydrocarbons contain solely ______ & _______ atoms.
Correct Answer(s)
A. Hydrogen
D. Carbon
Explanation
Hydrocarbons are organic compounds composed of only hydrogen and carbon atoms. This means that they do not contain any nitrogen or oxygen atoms. Hydrogen and carbon are the two elements that make up the building blocks of hydrocarbons, and their combination forms various types of hydrocarbon molecules, such as alkanes, alkenes, and alkynes. Nitrogen and oxygen can be found in other types of organic compounds, but in hydrocarbons, only hydrogen and carbon atoms are present.
8.
Select ALL that apply to Alkanes.
Correct Answer(s)
B. Saturated hydrocarbons
E. Carbon-carbon single bonds
Explanation
Alkanes are a type of hydrocarbon that consist of only carbon and hydrogen atoms. They are characterized by carbon-carbon single bonds, which means that each carbon atom is bonded to four other atoms. This results in a saturated hydrocarbon, as there are no available sites for additional bonds. Therefore, the correct answers are "Saturated hydrocarbons" and "Carbon-carbon single bonds".
9.
A __________ is an atom or group of atoms in a molecule that has a characteristic physical or chemical behavior.
Correct Answer(s)
functional group
Explanation
A functional group is an atom or group of atoms in a molecule that has a characteristic physical or chemical behavior. Functional groups are responsible for the reactivity and properties of molecules. They determine how a molecule will react with other substances and contribute to its overall function. By identifying and understanding the functional groups present in a molecule, scientists can predict its behavior and properties.
10.
The chemistry of organic compounds is determined by?
Correct Answer
C. Functional groups
Explanation
The chemistry of organic compounds is determined by functional groups. Functional groups are specific groups of atoms within a molecule that determine its chemical behavior and reactivity. They are responsible for the characteristic properties and reactions of organic compounds. Different functional groups can confer different properties to the molecule, such as acidity, basicity, polarity, and reactivity. They can also dictate the types of reactions that the molecule can undergo. Therefore, functional groups play a crucial role in determining the chemistry of organic compounds.

Select the three major attraction forces:
Correct Answer(s)
A. Dipole-Dipole
C. Hydrogen bonds
D. London dispersion force
Explanation
The three major attraction forces mentioned in the question are Dipole-Dipole, Hydrogen bonds, and London dispersion force. These forces are intermolecular forces that exist between molecules and contribute to their physical properties. Dipole-Dipole forces occur between polar molecules, where the positive end of one molecule is attracted to the negative end of another. Hydrogen bonds are a specific type of dipole-dipole force that occurs when a hydrogen atom is bonded to a highly electronegative atom (such as oxygen or nitrogen) and is attracted to another electronegative atom. London dispersion forces are temporary attractions between nonpolar molecules due to fluctuations in electron distribution.
