Question

Which of the following molecule has highest dipole moment?
a) CH3-CI
b) CH2Cl2
c) CHCl3
d) CCI4​

Answer 1

ch2cl2 has the highest dipole moment.

Explanation:

as 4cl molecules are distributed around the cancel each other dipole moment and become apolar .

now let's see the distribution of the molecules.

the resultant of two c-ch Bond and which increase the dipole moment however in chcl3 the resultant of 3 CCL Bond make some angle with Ch Bond which relatively decrease total dipole moment.

so as ch2cl2 has higher dipole moment it is more polar than chcl3.

I hope you got your answer.
