... The general formulas R-X, R-OH, and R-NH2 suggest two different ways to view these classes of compounds. One way is for us to imagine that an alkyl group R replaces H in HNH2 (ammonia), H-OH (water), and the hydrogen halides H-X (X = F, Cl, Br, or I). We can also view haloalkanes (R-X), alcohols (R- ...
