$C_2H_2$

Vedclass · Answer

(C) The bond length depends on the bond order and the hybridization of the carbon atoms.$C_2H_6$ $(ethane)$ has $sp^3$ hybridization with a $C-C$ single bond (bond length $\approx 154 	ext{ pm}$).$C_2H_4$ $(ethene)$ has $sp^2$ hybridization with a $C=C$ double bond (bond length $\approx 134 	ext{ pm}$).$C_2H_2$ $(ethyne)$ has $sp$ hybridization with a $C \equiv C$ triple bond (bond length $\approx 120 	ext{ pm}$).As the bond order increases, the bond length decreases.Therefore, $C_2H_2$ has the shortest $C-C$ bond length.

Which of the following has the shortest $C-C$ bond length?
