Electron density question

Postby William Cryer 1L » Sun Nov 19, 2017 10:41 am

Do the lone pairs of electrons in an atom count as a region of electron density? That is, will it effect the type hybridization (sp, sp2, etc)?

It will. For example, NH3 has a lone pair in N and its hybridization is sp3.

Yeah it does! Here's a helpful chart http://web.gccaz.edu/~chriy68124/VSEPR%20handout.pdf

Also, remember that you can use the AXE format to decipher the VSEPR geometric shape...

yes each lone pair counts as another region of electron density

Single, double and triple bonds count as one region of electron density.
Paired elections or an unpaired electron also count as one region of electron density.
