Arrange the following bonds in increasing order of bond length and provide the reason: $C-C$,$C=C$,$C\equiv C$.
(A) The bond length depends on the bond order. As the bond order increases,the bond length decreases.
$C-C$ (single bond) has a bond order of $1$.
$C=C$ (double bond) has a bond order of $2$.
$C\equiv C$ (triple bond) has a bond order of $3$.
Therefore,the increasing order of bond length is: $C\equiv C < C=C < C-C$.
$C-C$ (single bond) has a bond order of $1$.
$C=C$ (double bond) has a bond order of $2$.
$C\equiv C$ (triple bond) has a bond order of $3$.
Therefore,the increasing order of bond length is: $C\equiv C < C=C < C-C$.
