Question

(a) CH2Cl2 1 The C-H bond is polar.
The net dipole points from the C atomto the H atom.
The C-Cl bond is nonpolar.
The C-Cl bond is polar.
The C-H bond is nonpolar.
The molecule is nonpolar.
The net dipole points from the C atomto the midpoint of the two Cl atoms.

CHCl3 2 The net dipole points from the C atomto the H atom.
The C-Cl bond is nonpolar.
The C-Cl bond is polar.
The net dipole points from the C atomto the midpoint of the three Cl atoms.
The C-H bond is nonpolar.
The C-H bond is polar.
The molecule is nonpolar.

Explanation / Answer

a) The correct options are : i) The C-H bond is polar (different electronegativities ofboth atoms) iv) The C-Cl bond is polar (different electronegativities ofboth atoms) vii) The net dipolepoints from the C atom to the midpoint of the two Cl atoms. (sinceboth Cl are identical, resultant is at

the midpoint)
