Answer 2

Answer:

The correct answer is Option C: $CCl_4$

Explanation:

Even though $CCl_4$ has polar bonds, its dipole moment is zero due to the molecule's tetrahedral structure, which makes it extremely symmetrical and causes the four polar bonds to cancel one another out to create no dipole moment.

• When a molecule's core atom has four bonds and no lone pairs, the molecule is said to be tetrahedral.

• A dipole moment is a unit used to describe how far apart two electrical charges are from one another. Dipole moments are a vector quantity.

• A covalent link between two atoms that shares electrons unevenly is known as a polar bond. As a result, the molecule has a slight positive charge on one end and a slight negative charge on the other.
