Chemistry - Shapes (polar/nonpolar, sym/nonsym.)

What does a .3 or higher E.N.D mean?

Polar Covalent Bond.

If there is a polar covalent bond, what are the molecule types?

If symmetrical = non polar. If non-symmetrical = polar.

What does a 0, .1, or .2 E.N.D. mean?

Non-polar covalent bond

If there is a non-polar covalent bond, what is the molecule type?

Non-polar

Linear (0 lone pairs, 2nd electron group)

Symmetrical, non-polar molecule.

Trigonal Planar

3 electron groups, 0 lone pairs. Symmetrical, so non-polar molecule.

Bent (1 lone pair, 3 electron groups)

Not symmetrical, so polar.

Tetrahedral

0 lone pairs, 4 electron groups. Symmetrical, so non-polar molecule.

Trigonal Pyramidal

1 lone pair, 4 electron groups. Not symmetrical, so polar molecule.

Bent (2 lone pairs, 4 electron groups)

Not symmetrical, so polar.

Trigonal Bipyramidal

0 lone pairs, 5 electron groups. Symmetrical, so non-polar molecule.

Seesaw

1 lone pair, 5 electron groups. Not symmetrical, so polar molecule.

T-Shaped

2 lone pairs, 5 electron groups. Not symmetrical, so polar molecule.L

Linear (3 lone pairs, 5 electron groups)

Symmetrical, so non-polar molecule.

Octahedral

0 lone pairs, 6 electron groups. Symmetrical, so non-polar molecule.

Square Pyramidal

1 lone pair, 6 electron groups. Non-symmetrical, so polar molecule.

Square Planar

2 lone pairs, 6 electron groups. Symmetrical, so non-polar molecule.
