Solution:
QUESTION: 3

The correct non-linear and iso-structural pair is:

Solution:

In B the central atoms are S and I+ respectively, having 6 e- each and the others are from G-VII. Hence, they will have the same lone pair repulsion.

Hence B is correct.

Solution:
QUESTION: 6

Which among are super valent species:

(I) NO
(II) NO2
(III) PCl5
(IV) SF6

Solution:
QUESTION: 7

Correct order of bond angles is:

Solution:

Electronegativity decreases down the group, the electron density also decreases and consequently the repulsive interactions between the electron pairs also decrease thereby decreasing the bond angle H-M-H

 

QUESTION: 8

The compound pair which shows correct order of angle:

(I) NH3 > PH3
(II) H2S < H2O
(III) NO2+ > NO2
(IV) NO2+ > NO2
(V) NO2 > NO2+

Solution:
QUESTION: 9

The bond energies of H2, F2 and Cl2 decreases in the following order:

Solution:
