Consider the following molecules :
`H_(2)O H_(2)S H_(2) Se H_(2)Te `
`I II III IV`
Arrange these molecules in increasing order of bond angles

Options

A. `I lt II lt III lt IV`
B. `IV lt III lt II lt I`
C. `I lt II lt IV lt III`
D. `II lt IV lt III lt I`

Answer

B

Explanation

As the electronegatively of central atom increases the bond angle increased due to repulsion between pond pair and bond pair as bond pairs are more close to the central atom.
