Which of the following is the correct order for increasing bond angle ?

Options

A. `Nh_(3) lt PH_(3) lt AsH_(3) lt SbH_(3)`
B. `H_(2)O lt OF_(2) lt Cl_(2)O`
C. `H_(2)Te^(+) lt H_(3)Se^(+) lt H_(3)S^(+) lt H_(3)O^(+)`
D. `BF_(3) lt BCl_(3) lt BBr_(3) lt BI_(3)`

Answer

C

Explanation

Correct order of bod angle :
(a) `NH_(3) lt PH_(3) lt AsH_(3) lt SbH_(3) ` (As E.N. value of `C.A. uarr` bond angle `darr`)
(b) `OF_(2) lt OH_(2) lt OC l_(2)`
(c ) `H_(3)Te^(+) lt H_(3)Se^(+) lt H_(3)S^(+) lt H_(3)O^(+)`
(d) `BF_(3)=BCl_(3)=BBr_(3)=BI_(3)`
