Which of the following statement is true ?

Options

A. The dipole moment of `NF_(3)` is more than `NH_(3)`
B. trans `-2,3-`dichloro`-2-`pentene does not have net permanent dipole moment.
C. Carbono tetrachloride has no net dipole moment because of its regular tetrahedral strcture.
D. Dipole moment is zero for sulphurdioxide molecule.

Answer

3

Explanation

`(1)`
So `NH_(3)` has higher dipolmoment than `NF_(3)`.
`(2)`
It has some dipole moment due to unsymmetrical molecule.
`(3)`
It does not have dipole moment due to symmetrical molecule.
`(4)`
It has some dipole moment due to unsymmetrical molecule.
