-\boldsymbol{C H}\left(\boldsymbol{C}_{6} \boldsymbol{H}_{5}\right)- \) The IUPA

\( \boldsymbol{C H}_{3}-\boldsymbol{C H}\left(\boldsymbol{C H}_{3}\right)-\boldsymbol{C H}\left(\boldsymbol{C}_{6} \boldsymbol{H}_{5}\right)- \) \( N H_{2} \) The IUPAC name of the compound is :

  • A. \( 1- \) Amino -1 - phenyl - 2 - methyl propane
  • 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.
