Question

Why does cycloalkanes undergo ring opening reaction rather than addition reaction?

Answer 1

The higher cycloalkanes do notundergo addition reactions but give substitution reactions. Cyclopropane and its derivatives are most reactive and least stable where as, cyclobutaneis less reactive and cyclopentane isstill less reactive more stable.

Answer 2

The higher cycloalkanes do not undergo addition reactions but give substitution reactions. Cyclopropane and its derivatives are most reactive and least stable where as, cyclobutane is less reactive and cyclopentane is still less reactive more stable.
Cycloalkenes and cycloalkynes undergo the ordinary addition reactions of ... Cyclopropene , cyclopropyne, cyclobutene, and cyclobutyne also undergo ring‐opening reactions.
