Chemistry Question from JEE Main 2023 · 1 February, Shift 2

The structures of the major products A, B and C in the following reaction sequence are:

CH3CH2CH2CH(CH3)CHO  →NaCN, H2ONaHSO3, dil. HCl  [A]  →LiAlH4  [B]\mathrm{CH_3CH_2CH_2CH(CH_3)CHO}\;\xrightarrow[\mathrm{NaCN,\,H_2O}]{\mathrm{NaHSO_3,\,dil.\,HCl}}\;[A]\;\xrightarrow{\mathrm{LiAlH_4}}\;[B]

[A]  →ΔHCl/H2O  [C][A]\;\xrightarrow[\Delta]{\mathrm{HCl/H_2O}}\;[C]
