SP3

Here is my little trick:

For every “thing” we have around an atom, we count. One “thing” is a single bond, a double bond, a triple bound, or a lone pair. They all ONLY count as 1 thing, that’s it.

Two things is SP

Three things is SP2

Four things is SP3

In PCl3, we have:

3 bonds, and 1 lone pair, so we have 4 things. 4 things is SP3.

What about CO2? It looks like

O = C = O

Hybridization of Carbon:

2 double bonds, no lone pairs, 2 things is SP

Oxygen?

1 double bond, 2 lone pairs, 3 things SP2

Just remember that a single bond, double bond, and triple bond count as only 1 thing. And if you forget the SP3 or SP2, the number that comes after the P is the number of things, minus 1. Or, another way is the amount of things matches the amount of letters we have.

Two things is SP, that is two letters, S and P

Three things is SP2, that is three letters, S, P, P…
