Question

what type of compound is $\ce{ch_{2}=ch-ch_{2}-ch_{3}}$?
a branched alkane
b alkane
c cycloalkane
d alkene

Explanation:

• Alkanes have the general formula \(C_nH_{2n + 2}\) and only single - bonds (\(C - C\)). Branched alkanes are alkanes with side - chains. Cycloalkanes have a ring structure.
• Alkenes have the general formula \(C_nH_{2n}\) and contain at least one carbon - carbon double bond (\(C = C\)). The given compound \(CH_2=CH - CH_2 - CH_3\) has a \(C = C\) bond.

Answer:

D. alkene
