-
Alkene
-
Phenol
Correct Answer
A. AlkeneExplanation
The correct answer is alkene. An alkene is a type of hydrocarbon that contains a carbon-carbon double bond. It is characterized by the presence of unsaturation, which means it has fewer hydrogen atoms than the corresponding alkane. Alkenes are highly reactive and can undergo addition reactions to form new compounds.Rate this question:

Correct Answer
A. AlkeneExplanation
The correct answer is alkene. An alkene is a type of hydrocarbon that contains a carbon-carbon double bond. It is characterized by the presence of a functional group called a double bond, which gives it its unique chemical properties. Esters, alkanes, and carboxylic acids do not have double bonds and therefore do not belong to the alkene functional group.Rate this question:

Correct Answer
A. Carboxylic acidExplanation
The functional group present in the compound is a carboxylic acid. Carboxylic acids are characterized by the presence of a carboxyl group, which consists of a carbonyl group (C=O) and a hydroxyl group (-OH) attached to the same carbon atom. In the given options, only "carboxylic acid" corresponds to this functional group. Esters have a carbonyl group and an alkyl group attached to an oxygen atom, ethers have two alkyl or aryl groups attached to an oxygen atom, and acid anhydrides have two carbonyl groups attached to an oxygen atom.Rate this question:

Alkene
Correct Answer
A. Primary alcoholExplanation
A primary alcohol is a type of alcohol where the hydroxyl (-OH) group is attached to a carbon atom that is bonded to only one other carbon atom. In this case, the functional group of the compound is the hydroxyl group (-OH) attached to a primary carbon atom. This is different from a tertiary alcohol, where the hydroxyl group is attached to a carbon atom that is bonded to three other carbon atoms. A ketone is a compound that contains a carbonyl group (C=O) bonded to two other carbon atoms. An alkene is a compound that contains a carbon-carbon double bond.Rate this question:

Correct Answer
A. AlkaneExplanation
The given functional group is alkane. Alkanes are hydrocarbons that consist of only single bonds between carbon atoms and are saturated compounds. They are characterized by the general formula CnH2n+2. In this case, the term "tertiary alcohol," "secondary alcohol," and "primary alcohol" refer to different types of alcohols, which contain the functional group -OH attached to a carbon atom. However, the term "alkane" refers to a different type of compound that does not contain the -OH functional group. Therefore, the correct answer is alkane.Rate this question:

Ester
Correct Answer
A. AlkaneExplanation
The correct answer is alkane. Alkane is a type of hydrocarbon that consists of only single bonds between carbon atoms. It is a saturated hydrocarbon and does not contain any functional groups. In contrast, alkenes have a carbon-carbon double bond, ethers have an oxygen atom bonded to two carbon atoms, and esters have a carbonyl group bonded to an oxygen atom and an alkyl group. Therefore, alkane is the only option without a functional group.Rate this question:

Carboxylic acid
Correct Answer
A. Carboxylic acidExplanation
The functional group in the given list is carboxylic acid. Carboxylic acids are organic compounds that contain a carboxyl group, which consists of a carbonyl group (C=O) and a hydroxyl group (OH) attached to the same carbon atom. This functional group is commonly found in organic acids, such as acetic acid and formic acid, and it is responsible for their acidic properties. Carboxylic acids are important in various biological processes and have applications in industries such as pharmaceuticals and food production.Rate this question:

Alkene
Correct Answer
A. PhenolExplanation
Phenol is the correct answer because it is a functional group that consists of a hydroxyl group (-OH) attached to an aromatic ring. It is commonly found in compounds such as antiseptics, disinfectants, and dyes. Cycloalkane, cycloalkene, and alkene are not the correct answers as they represent different types of hydrocarbon compounds without the presence of a hydroxyl group.Rate this question:

A. EsterExplanation
The correct answer is ester. Ester is a functional group that is characterized by the presence of a carbon-oxygen double bond (C=O) and an oxygen atom bonded to a carbon atom through a single bond (C-O). Esters are commonly found in many organic compounds, such as fats, oils, and fragrances. They are formed by the reaction between an alcohol and an organic acid, resulting in the elimination of water. Esters have a pleasant smell and are often used as flavorings and fragrances in various products.Rate this question:

The correct answer is ether. An ether is a functional group that consists of an oxygen atom bonded to two alkyl or aryl groups. It is characterized by the general formula R-O-R', where R and R' can be any organic group. Ethers are commonly used as solvents and have a wide range of applications in organic synthesis. They are distinct from carboxylic acids, aldehydes, and esters, which have their own unique functional groups and chemical properties.Rate this question:
