For each of the following element please....?

Question

NH2Cl, Cl2O, AsH5, AlH3, CCl2F2, O3 explain wether they are polar or non polar. For each polor molecule label the elecronegativity of each atom and show where the partial charges reside. Thanks so much (please no dumb answers).

Answer 1

NH2Cl: Polar. The electronegativity of Cl=3.0, of N=3.0, so neutral, and H=2.2, so a little (+). Also, the molecule is unsymmetrical as to charge distribution. N=Cl=(-).

Cl2O: Polar. The electronegativity of Cl=3.0, O=3.5, and the molecule is an unsymmetrical boomerang, with (-) head and (+) wings.

AsH5. Nonpolar. There is electronegativity difference, but the molecule is overall symmetrical as to charge distribution (trigonal bipyramid).

AlH3. Nonpolar. Same argument. Trigonal

CCl2F2. Polar. Electronegativity of F=4.0, Cl=3.0, C=2.4. F's point in one direction; Cl's in another.

O3. Nonpolar. Electronegativity of O=3.5. Molecule is unsymmetrical bent, but no unequal distribution of charges.
