Identify the correct order :

A

`[V(CO)_(6)]^(-) lt [Cr(CO)_(6)]`(C-O bond length order )

B

`H_(2) lt He` (Boiling point order)

C

`NH_(2)^(-) gt H_(2)O` (Bond angle order)

D

All are correct

Text Solution

Verified by Experts

The correct Answer is:
C

`H_(2)OgtNH_(2)^(-)`
(Bond angle)
(b) B. P. of `H_(2) gt He`, due to greater surface area of `H_(2)`
(a) C-O B. L. order `[V(CO)_(6) ]^(-) gt [Cr (CO)_(6)]`
