Chemical Bonding & Molecular Structure

(A) According to MOT, number of Bonding electrons and number of antibonding electron in Ne2 is same
So, BO=‌

Nb−Na

2

is zero
(A) is correct
(B)
‌F2⇒σ152σ15*2σ252σ25*2σ2p22π2px2=π2py2
‌π2px*2=π2py*2σ2p2*
HOMO of F2 is π-type not σ-type
(B) is incorrect
(C) BE∝BO
BO of O2 is =2
BO of O2+is =2.5
BE of O2+>BE of O2
(C) is incorrect
(D) Bond length of B2=118‌pm
Bond length of Li2=267‌pm
B.L. of Li2> B.L. of B2
(D) is correct
