The C-C bond length is shortest in
C2H6
C2H4
C2H2
C2H5Cl
As we learnt in
Bond Order -
Bond order is defined as one half the difference between the number of electrons present in the bonding and the antibonding orbitals.
- wherein
We know thet bond length
bond order is highest at 3 with C2H2
C-C bond length will be shortest.
