Question

Propose a mechanism from the reaction in the box

Answer 1

Answer #1

2. The order of the bond strength is a<b<c.

Single bond contains 1 σ bond, double bond contains 1σ and 1π bond. Triple bond contains 1σ and 2 π bonds.

Triple bond has strongest bond. As the bond order increases from a to c the bond length decreases and bond strength increases.
