The study of carbon- containing compounds and their properties is called organic chemistry. Besides carbon atoms, organic compounds also can contain hydrogen, oxygen, and nitrogen atoms (as well as other types of atoms). A common trait of simple organic compounds is to have Lewis structures in which all atoms have a for-mal charge of zero. Consider the following incomplete Lewis structure for an organic compound called histidine (one of the amino acids, which are the building blocks of proteins found in human bodies):
Draw a complete Lewis structure for histidine in which all atoms have a formal charge of zero. What are the approximate bond angles about the carbon atom labeled 1 and the nitrogen atom labeled 2?
