Question

Which of the following compounds can exist in enantiomeric (i.e., D and L) forms?

• A. 3-methyl butanoic acid
• B. cis-2-butene
• C. isopropyi amine
• D. 1-methyl butanamine

Answer 1

Answer: (D)

1-methyl butanamine

Answer 2

1-methyul butanamine, $C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-\underset{*}{\overset{\begin{smallmatrix} C{{H}_{3}} \\\ | \end{smallmatrix}}{\mathop{CH}}}\,-N{{H}_{2}}$ has one chiral carbon so, it can exist in enantiomeric forms.
