furnishes a single primary alcohol B. Whereas reaction ofA with an excess of methylmagnesium bromide
furnishes two alcohols B and C. In the NMR spectrum, compound B exhibits signals at 6 3.8 (2H, d, J = 7
Hz), 1.8(1 H, m). 1.6( 1 H, brs, exchangeable with D20 ) and 0.9 (6 H, d, J = 7.2 Hz). Identify the structures
of the compounds A, B and C, and explain the reactions.
