Solution: Consider the Lewis structure for glycine, the simplest amino acid: What are the approximate bond angles about each of the two carbon atoms?

Problem

Consider the Lewis structure for glycine, the simplest amino acid: An N with one pair of dots is single bonded left and below to H and right to C.  That C is single bonded above and below to H and right to C.  That C is double bonded above to O (which has two pairs of dots) and right to O (which also has two pairs of dots). That O is single bonded right to H.

What are the approximate bond angles about each of the two carbon atoms?
