Detailed Solution

Given data:

It is given to identify the hybridization of triply bonded carbons, carbon–carbon triple bond length and bond strength of carbon-carbon triple bond.

Formula/concept: Alkynes

Detailed solution:

The carbon-carbon triple bond is generally called alkynes which is represented as $H C \equiv C H$ . The carbon here are $s p$ - hybridized. Triple bond is the shortest and hence, difficult to break. The bond length of this triple bond is1. $20 A °$ . Alkynes with $s p$ -hybridization possess a bond strength of 825 ${kJMol}^{- 1}$ .
