Arrange the following molecules in the increasing order of bond angle.
`underset(I)(H_(2)O) underset(II)(H_(2)S)underset(III)(H_(2)Se) underset(IV)(H_(2)Te)`

A

`I lt II lt III lt IV`

B

`IV lt III lt II lt I`

C

`I lt III lt II lt IV`

D

`IV lt II lt III lt I`

Text Solution

Verified by Experts

The correct Answer is:
B
lp-bp repulsion is maximu, in `H_(1)Te` due to least electronegativity of Te and minimum in `H_(2)O` due to high electronegavity of O.
