Give any easy tricks to find out hybridisation (sp, sp2, sp3...) for chemical compounds?
As you requested Here’s a shortcut for how to determine the hybridization of an atom in a molecule.
This will prevent quite a few time.
Here’s what you do:
Look on the atom.
Count the quantity of atoms connected to it (atoms – not bonds!)
Count the variety of lone pairs attached to it.
Add these two numbers together.
If it’s 4, your atom is sp3.
If it’s 3, your atom is sp2.
If it’s 2, your atom is sp.
(If it’s 1, it’s possibly hydrogen!)
This works in at the least 95% of the cases you'll see in Org 1.
Hope helpful.
