Bond angle in PH(3) is...

Bond angle in `PH_(3)` is

A

Much less than `NH_(3)`

B

Much less than `PF_(3)`

C

More than `NH_(3)`

D

More than `PF_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A, B
Bond angles `{:(NH_(3)gt,PF_(3)gt,PH_(3),,),((107^(@)),(98^(@)),(94^(@)),,):}`
`PF_(3) gt PH_(3)` F-atoms are larger than H-atoms and need more space
`NH_(3) gt PH_(3)` Bond angle decreases down group 15 hydrides .
