- B. 2- Methyl-1- phenyl propan-1 - amine
- C. 2- Methyl-1- amino -1 - phenyl propane
- D. 1- -Isopropyl -1 - phenyl methyl amine
Step-by-step solution
The compound has a three-carbon chain (propane) with an amino group on C1, a phenyl group on C1, and a methyl group on C2. The IUPAC name is derived by naming the parent chain as propan-1-amine, with substituents listed alphabetically: 2-methyl and 1-phenyl, giving 2-methyl-1-phenylpropan-1-amine. Options A and C incorrectly use 'amino' as a prefix instead of suffix, and option D is incorrect.
