1. Even though you have seen the basics of organic nomenclature, there are other groups that

Question

are quite common. Give the general formula for the following:
a. nitrile group (draw its basic structure showing the triple bond)
b. anhydride group (draw its basic structure showing the double bonds)
c. amino acid group
d. thiol group

Answer 1

a. The general formula for the nitrile group is RC≡N, where R represents any alkyl or aryl group.
b. The general formula for the anhydride group is (RCO)2O, where R represents any alkyl or aryl group.
c. The general formula for the amino acid group is NH2-CHR-COOH, where CHR represents a variable carbon chain.
d. The general formula for the thiol group is R-SH, where R represents any alkyl or aryl group.
