(d) None of these

Answer 1

Explanation:

Which of the following conceivable structures for CCl4 will

have a zero dipole moment ?

(a) Irregular tetrahedron

(b) Square planar

(c) Square pyramid (carbon at apex)✔️

(d) None of these

Answer 2

The structure of CCl4 which will have zero net dipole moment is tetrahedral. therefore the correct answer to this question will be (option d) None of these.

The structure of CCl4 is tetrahedral. Although the C-Cl bond is polar in nature in the tetrahedral structure of CCl4 the carbon atom is at the center while the Cl atoms occupy the four corners of the tetrahedron.

The arrangement of Cl atoms is in such a way that they cancel out each other's polar nature and the net dipole moment of CCl4 is zero.
