Diamond

Vedclass · Answer

(A) The bond length is inversely proportional to the bond order.In $Diamond$, the $C-C$ bond is a pure single bond (bond order = $1$, bond length = $154 	ext{ pm}$).In $Graphite$, the $C-C$ bond has partial double bond character (bond order = $1.33$, bond length = $141.5 	ext{ pm}$).In $Benzene$, the $C-C$ bond has partial double bond character (bond order = $1.5$, bond length = $139 	ext{ pm}$).In $Ethene$ $(CH_2=CH_2)$, the $C-C$ bond is a double bond (bond order = $2$, bond length = $134 	ext{ pm}$).Therefore, the bond length is maximum in $Diamond$.
