Practice sketching molecules, using the number of bonds an atom can form as a guide. a. SH2
b. Below is one enantiomer of lactic acid. Draw the other enantiomer. (Remember a pair of enantiomers is two molecules that are mirror images of each other.)

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.
