Question

Which piece of information do you need to determine whether a molecule is an alkene or an alkane?

Answer 1

Step-by-step explanation:

Hydrocarbons are molecules made of carbons and hydrogens. There are 3 categories of hydrocarbons: alkanes, alkynes, and alkenes. Alkanes are saturated hydrocarbons that have only single carbon-carbon bonds, and have a general formula of CnH2n+2. Alkenes are unsaturated hydrocarbons that have at least one carbon-carbon double bond, and have a general formula of CnH2n. Alkynes are also unsaturated hydrocarbons, but have at lease one carbon-carbon triple bond, and their general formula is CnH2n-2.
