Which one of the following arrangements of molecules is correct on the basic of their dipole moments?

A

`NH_(3) gt NF_(3) gt BF_(3)`

B

`NF_(3) gt BF_(3) gt NH_(3)`

C

`NH_(3) gt BF_(3) gt NF_(3)`

D

`BF_(3) gt NF_(3) gt NH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
dipole moment depends upon
(i) Electronegativity difference polarity of charge magnitude
hence, the corect order is ltBrgt `NH_(3) gt NF_(3) gt BF_(3)`.
