Cyclobutane is less reactive than cyclopropane. Justify.
The C-C-C bond angle in the cyclobutane molecule is 90o90o and in cyclopropane 60o60o. It demonstrates that in cyclobutane the difference between the bond angle of the tetrahedral (109o28 ′ 109o28 ′ ) and cyclopropane is smaller. In other words, compared with cyclobutane, cyclopropane is under severe strain and is hence more reactive.
