The molecular formula for 2-butyne , propyne, and 2-butene is to be determined. Concept introduction: The molecular formula is the simplest representation of the compound that tells about the number of each atoms present in the compound. Alkenes are unsaturated hydrocarbons and contain a C=C double bond. Alkynes are unsaturated hydrocarbons contains a triple bond. The suffix ‘-yne’ is used for naming alkynes and the suffix ‘-ene’ is used for naming alkenes.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
