(1) Which is the correct statement about S2 (g) molecule which forms above 1000°C? Molecular orbital theory of S2 is found to be similar to that of O2 molecule.
(A) it is paramagnetic molecule having 2 unpaired electron.
(b) its bond order is two but both should be ∩ bonds.
(C) The HOMO level in S2 (g) should be ∩* 3p.
(D) Bond order is exactly same with O2, so bond strength should also be exactly same.

29D is false because it is not necessary that molecules with same bond order have same bond strength .....moreover the tendency to form π bonds decreases down the group...... so double bond in case of sulphur will not be as strong as it is in oxygen as 3p orbits are lager in size.
