15. It is believed that Alexander the Great was poisoned by an organic compound known as Strychnine. The structure of Strychnine is shown below. Identify the functional groups present in this molecule. a NT H "H b d A. a = tertiary amide, b = tertiary amine, c = alkene, d = ether B. a = ketone, b = secondary amine, c = alkene, d = ether C. a secondary amide, b = tertiary amine, c = alkyne, d = alcohol D. a = ketone, b = tertiary amide, c = alkyne, d = ether
Functional group: The atom or group of atoms of a molecule which can modify physical and chemical properties of the molecule is called functional group.
Keto functional group - the carbon of C=O connected directly with two other carbon atoms - (C-C(O)-C).
Ether functional group- The oxygen directly connected with two carbons - (C-O-C)
Primary Amine functional group - The Nitrogen is connected with one carbon unit and two hydrogens - (C-NH2)
Secondary amine - The nitrogen is directly connected with two carbon units and one hydrogen - (C-NH-C)
Tertiary amine - The nitrogen is directly connected with three carbons - (C)3N.
Alkene - The double bond is observed between two two carbon units - C=C.
Alkyne - Triple bond is observed between two carbon units -
Alcohol - The carbon is directly connected with OH - (C-OH)
Tertiary amide - The nitrogen of C=O directly connected with two carbon units - (C(O)-N(C)2
Note: the direct bonds with carbons are shown in the above functional groups, the hydrogens connected to the carbons are omitted.
