Answer:
Li2,B2,F2
Explanation:
Li2,B2,F2...have bond order = 1 ( by Molecular Orbital Theory) hence there bond lengths are greater than C2 whose bond order is 2 ( bond order is inversely proportional to bond length..i.e, greater the bond order lesser is its bond length).
Whereas for N2 has bond order 3 therefore lesser bond length and O2 has same bond order.
