Nomenclature for Alkanes Questions and Answers

1.

CH₄

Explanation
Methane is the simplest alkane and a key component of natural gas, used widely as a fuel and chemical feedstock. It's a colorless, flammable gas with a tetrahedral structure. Combustion produces carbon dioxide and water, while halogenation yields various chlorinated compounds. Though crucial in energy production and chemical manufacturing, methane is a potent greenhouse gas with a significant impact on global warming.

4.

Explanation
Butane (C4H10) is a saturated hydrocarbon with four carbon atoms and ten hydrogen atoms. It exists as two structural isomers: n-butane, with a linear carbon chain, and isobutane, with a branched structure. Both isomers are colorless, flammable gases at room temperature. Butane has a boiling point of -0.5°C (n-butane) and -11.7°C (isobutane), and it is commonly used as a fuel and in the production of synthetic rubber.

Rate this question:
5.

Explanation
Isobutane (C4H10) is a branched alkane and an isomer of butane, featuring a central carbon atom bonded to three methyl groups and one hydrogen in a tetrahedral geometry. This structure gives it a boiling point of -11.7°C and a melting point of -159.6°C, making it a colorless, flammable gas at room temperature.
