Question

State True or False.

All the carbon atoms in bicyclobutane are $s{p}^2$-hybridized.

• A. True
• B. False

Answer 1

The correct option is B False

In bicyclobutane all carbons atoms are $s{p}^3$ hybridized. In order to form a ring compound with four carbons and a bridging bond , the carbons in the ring are forced to form ${90}^o$ bond angles; this is much smaller than the preferred ${109.5}^o$ bond angles.
