Vedclass · Accepted Answer

Formed by $sp - sp$ hybridised carbon atoms (as in alkynes)

Vedclass · Answer

(C) The strength of a $C - C$ bond depends on the percentage of $s$-character in the hybrid orbitals.Greater $s$-character leads to shorter and stronger bonds.For $sp$ hybridization,$s$-character is $50\%$.For $sp^2$ hybridization,$s$-character is $33.3\%$.For $sp^3$ hybridization,$s$-character is $25\%$.Therefore,the order of bond strength is $sp - sp > sp^2 - sp^2 > sp^3 - sp^3$.

Which of the $C - C$ bond is strongest?
