2sp2 vs sp2

[Isabel Day 1D]

What does it mean when there's a 2 in front of the hybridization? For example, in question 17 of marshmallow many of the sigma bonds have C2sp2 or N2sp hybridizations.

The two specifies what row the element is in, so since carbon is in the second row it has the 2 in front of the p. Unless specified, sp^2 can still be the correct hybridization for carbon.

[Lauren Stack 1C]

The two is simply signifying the number of the row that the element is found. For example, you could apply this to other rows and put a 1 in front of the s when describing the hybridization of something including a Hydrogen (1s).

You usually add the 2 i front of the sp2 when you are describing the hybridization of a bond. If you are just describing the hybridization of an individual molecule, I don't believe that you need the 2 in front.
