VSEPR notation

Postby Katherine Wu 1H » Sat Nov 16, 2019 10:54 pm

In CH2Cl2, would the VSEPR notation would be AX4?

In PCl3, would the VSEPR notation would be AX3E?

If not, please explain.

The VSEPR notation for CH2Cl2 is correct because there are four regions of electron density and the VSEPR notation for PCl3 is also correct because there are three atoms bonded with one lone electron pair.

You are correct

Yes, those VSEPR notations are correct and I believe the corresponding shapes would be tetrahedral and trigonal pyramidal (correct me if I am wrong please).

Yes, in CH2Cl2, the VSEPR notation would be AX4, corresponding to tetrahedral shape as well as bond angles of 109.5 degrees.

For PCl3, the VSEPR notation would be AX3E, corresponding to trigonal pyramidal as well as bond angles of less than 109.5 degrees.

It is helpful to memorize the notations in order to figure out the shape.

That's right
