Re: S character

The s character is the contribution of sigma type bond in hybridization, the more the s-character a bond has, the stronger and shorter the bond is.

Homework Question

I need help with a homework question: 2F.17
" Describe the structure of the formamide molecule, CH2O, in terms of hybrid orbitals, bond angles, and sigma bonds and pi bonds. The C atom is the central atom to which the other three atoms are attached."
How would you begin to answer this?
