Ch3br Polar Or Nonpolar

Can you predict whether each of the following molecules is polar or non-polar? 3

1. XeF4

2. NH3

3. CCl4

4. SF4

5. CH3Br

6. GaH3

1. Apolar The electron configuration of this molecule is octahedral, its geometry is square. If we look at the difference between the electrical negativity of an atom and its geometry, we will find non-polar molecules that are very smooth.

2. A polar ammonia molecule consists of an isolated pair that forms a liquid dopole moment resulting in a polar molecule.

3. The four non-polar binding moments cancel each other out due to the harmony of the molecules, so there is no liquid dupole moment.

4. The pole is an isolated pair in the sulfur tetrafluoride molecule and, due to its strange shape, has a sharp dopole moment.

5. Polar, this molecule is not compatible, so binding moments (difference in electrical negativity of atoms) do not cancel each other out.

6. Non-polar These molecules are very symmetrical (triangular plane geometry), binding moments cancel each other out and you have a non-polar molecule.
