Identify an optically active compound "X" whose molecular formula is C4H11N forms C4H9OH on reaction with HNO2.
Correct answer: A. 2−aminobutane
- A. 2−aminobutane
- B. N−methyl propaneamine
- C. N,N−dimethyl ethaneamine
- D. 1−aminobutanetane
Explanation
In 2-aminobutane (CH3 - CH2 - CHNH2 - CH3), all valency of the 2nd carbon atom is satisfied with four different groups, hence it is a chiral compound and optically active compound. CH3 - CH2 - CHNH2 - CH3 + HNO2 --> CH3 - CH2 - CHOH - CH3 + H2O + N2

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
