 Among the following the compound that do not containing P-P overlapping is ?

a) H2
b) BeCl2
c) F2
d) HF

Solution :- 

For p-p overlap both atoms must have unpaired electrons in p-orbitals.

H- $1s^1$

Be- $1s^2$$2s^2$

Cl- $1s^2$$2s^2$$2p^6$$3s^2$$3p^5$

F- $1s^2$$2s^2$$2p^5$

If you see here , only F and Cl have unpaired electron in vacant shell. 
But Cl is forming bond with Be which has s-orbital.
while F has 'p' orbital and it is shairing electron with other p-orbital of F.

Hence D is the correct answer . i.e. HF compound .
