Question

The u of CH4 and CCl4 is zero. Than prediction of its shape and give reason of its right shape.

I m challenging to all for this question.If anyone have a smart brain then give the answer. ​

Answer 1

CORRECT QUESTION:

The magnetic diople moment(μ) of CH₄ and CCl₄ is zero. Then predict its shape and give reason of its right shape.

GIVEN:

• The magnetic diople moment(μ) of CH₄ and CCl₄ is zero.

TO PREDICT:

• The geometry of CH₄ and CCl₄.

TO EXPLAIN:

• The reason for its right shape.

EXPLANATION:

• In CCl₄ four Chlorine atoms in order to decrease the repulsion between them will increase the distance between each other.

• This results in tetrahedral geometry.

• This tetrahedral geometry is also responsible for the zero magnetic diople moment of CCl₄.

• Magnetic diople moment due to C - Cl bond will be cancelled by those in opposite side.

• Also symmetry causes the net dipole moment to be zero.

• Same reason for CH₄.

• Magnetic diople moment due to C - H bond will be cancelled by those in opposite side.

• Here also symmetry causes the net dipole moment to be zero.

• Geometry of CH₄ is tetrahedral geometry.
