Which of the following statements about alkanes is true?
A
Alkanes are unsaturated hydrocarbons.
B
Alkanes have a general formula of CnH2n.
C
Alkanes contain only single bonds between carbon atoms.
D
Alkanes are more reactive than alkenes.
Verified step by step guidance
1
Understand the definition of alkanes: Alkanes are saturated hydrocarbons, meaning they contain only single bonds between carbon atoms.
Review the general formula for alkanes: The general formula for alkanes is CnH2n+2, not CnH2n.
Compare the reactivity of alkanes and alkenes: Alkanes are less reactive than alkenes because alkenes contain double bonds, which are more reactive than the single bonds in alkanes.
Evaluate the statement about saturation: Alkanes are saturated hydrocarbons, so the statement that they are unsaturated is incorrect.
Identify the correct statement: The statement 'Alkanes contain only single bonds between carbon atoms' is true, as it aligns with the definition of alkanes.
