Compound A has molecular formula C7H14O and reacts with sodium borohydride in methanol to form an alcohol. The 1 H NMR spectrum of compound A exhibits only two signals: a doublet (I = 12) and a septet (I = 2). Treating compound A with 1,2-ethanedithiol (HSCH2CH2SH) under acidic conditions, followed b
