which of the following explains the vsepr geometry of a carbon tetrachloride molecule? (5 points)

it is bent because there are four bonded pairs around carbon.

it is tetrahedral because there are four bonded pairs around carbon.

it is bent because there are two bonded pairs and two lone pairs around carbon.

it is tetrahedral because there are two bonded pairs and two lone pairs around carbon.

It is tetrahedral because there are four bonded pairs around carbon.

Explanation:

Carbon tetrachloride has carbon atom as central atom surrounded by four chlorine atoms.

By VSEPR theory:

The shape of a molecule is decided by the number of sigma bonds and lone pairs of electrons that the central atom possess and the repulsions between lone pairs and bond pairs.

Here there are 4 sigma bonds and 0 lone pairs.

Hybridisation number = no.of sigma bonds + no.of lone pairs.

                                    = 4 + 0 = 4

Then it is sp³ hybridised with tetrahedral geometry.

The shape becomes bent when central atom has lone-pairs due to bond pair - lone pair repulsions.
