Question

Quizplus · Accepted Answer

In unbranched hydrocarbons, each carbon atom is indeed connected to not more than two other carbon atoms, forming a straight chain. The C-C-C bond angle is not 180°; it varies depending on the hybridization of the carbon atoms (e.g., 109.5° for sp3 hybridized carbons in alkanes).
