Composition of a Bond

Postby Cindy Nguyen 1L » Wed Jun 13, 2018 11:52 pm

How do you identify the composition of a bond? I know how to figure out if the bond is a pi or sigma bond, and I know what hybridization an atom would have. For example, sigma(C2sp2, C2sp2). I know the sigma refers to a sigma bond, and the Cs refer to a bond between two carbon atoms. The sp2 refers to the hybridization of the orbitals. What does the 2 after the C mean?

Remember in class we discussed:

single bond = sigma bond
double bond = sigma bond + pi bond
triple bond = sigma bond + 2x pi bond

Carbon atom valance electrons in the second shell, hence the 2.
