Question

The molecules that will have dipole moment are -
CO2
CHCl3
H2O
CH4​

Answer 1

Answer:

CHCl3 & H2O

Explanation:

CO2  structure -->   O=C=O        so dipole moments due to O are cancelled out

In CH4 also, dipole moment is cancelled out....... but not in H2O and CHCl3

in H2O, both O atoms are at an angle of 104.5 degrees... so they are not cancelled and hence, have a net dipole moment.

In CHCl3, Chlorines are attached in tetrahedral manner and have a net dipole moment.
