Step by step solution
Functional groups
Certain functional groups are designated differently if other functional groups are also present.If a molecule contains a double bond and no other functional group is present, then it is an alkene, but it is considered a C-C double bond if other functional groups are present.
Step 2(a): The functional groups in Methionine
In Methionine, there is a total of three functional groups present- one sulfide (-S) group, one carboxylic acid (-COOH) group, and one amine () group.
Methionine
Step 3(b): The functional groups in Ibuprofen
In Ibuprofen, there are two functional groups present- one carboxylic acid (-COOH) group and one aromatic ring.
Ibuprofen
Step 4(c): The functional groups in Capsaicin
In Capsaicin, there are a total of five functional groups present- one alcohol (-OH) group, one ether (-ROR) group, one amide (-CONH) group, one C-C double bond, and one aromatic ring.
Capsaicin
