Question

the carbon atoms in saturated hydrocarbons ______. a have only single bonds b contain at least one double bond c contain at least one triple bond d contain a benzene ring

Explanation:

Saturated hydrocarbons are defined as hydrocarbons in which all carbon - carbon bonds are single bonds. Unsaturated hydrocarbons have double or triple bonds (for example, alkenes have double bonds and alkynes have triple bonds). Benzene rings are part of aromatic hydrocarbons which are a type of unsaturated hydrocarbons (due to the delocalized pi - electron system which can be thought of as a form of unsaturation in terms of bonding characteristics compared to alkanes).

Answer:

A. have only single bonds
