Which of the following correctly describes the role of alkanes in organic chemistry?
A
Alkanes are aromatic compounds with alternating single and double bonds.
B
Alkanes are saturated hydrocarbons with single bonds between carbon atoms.
C
Alkanes are compounds containing a carbonyl group.
D
Alkanes are unsaturated hydrocarbons with double bonds between carbon atoms.
Verified step by step guidance1
Identify the definition of alkanes: Alkanes are a class of hydrocarbons.
Understand the term 'saturated hydrocarbons': This means that alkanes have only single bonds between carbon atoms, with each carbon atom forming four single covalent bonds.
Differentiate alkanes from other types of hydrocarbons: Alkenes and alkynes are unsaturated hydrocarbons, containing double and triple bonds, respectively.
Recognize that alkanes do not contain functional groups like carbonyl groups, which are characteristic of other organic compounds such as ketones and aldehydes.
Conclude that the correct description of alkanes is that they are saturated hydrocarbons with single bonds between carbon atoms.
