MCQ
Amongst the given set of reactants, the most appropriate for preparing 2°amine is _____.
- A2° R-Br + NH3.
- B2° R-Br + NaCN followed by H2/Pt.
- C1° R-NH2 + RCHO followed by H2/Pt.
- D1° R-Br (2 mol) + potassium phthalimide followed by H3O+/heat.
✓
Answer
- 1° R-NH2 + RCHO followed by H2/Pt.
Explanation:
$\text{R}-\text{NH}_2+\text{O}=\text{HCR}\xrightarrow[\text{animation}]{\text{Reductive}}\text{R}-\text{N}=\text{CHR}\xrightarrow[\text{Reductiion}]{\text{H}_2/\text{pt}}\text{RNH}-\text{CH}_2\text{R}$
