Doubt in P block


Answer is AB

C and D won’t be answer as S2 and F2 don’t have same diff is bonding and anti bonding electrons
And as F2 B.O is 1 then for Y2 also B.O must be one.
Cl2 has more electron gain enthalpy than F2 and diff is also same so B crct.
But iam not sure of A ?

@Bhuvanitha_2020 2 molecules of fluorine is given which confused me. SO I thought of 2*1=2 and its BDe greater than F2

And BDE ORDER IS CL2>BR2>F2
So if B is right. A IS also right but the 2 nolecule part is confusing

It is written two molecules F2 and Y2 means not two molecules of F2

Oh They could have wrote simply one molecule. ThanKS @Bhuvanitha_2020 @Achyut_2020
