0.44 g of a monohydric alcohol when added to methylmagnesium iodide in ether liberates at STP, 112 cm3 of methane. With PCC the same alcohol forms a carbonyl compound that answers silver mirror test. The monohydric alcohol is
H3C-CH(OH)-CH2-CH3
(CH3)3C-CH2OH
H3C-CH(OH)-CH2-CH2-CH3
(CH3)2CH-CH2OH
B.
(CH3)3C-CH2OH
Molecular mass of alcohol =
Since, alcohol oxidised with PCC [Pyridinium chloro chromate or Corey's reagent C5H5NH+CrO3Cl-] to form a carbonyl compound (aldehyde), which gives positive silver mirror test hence carbonyl compound must be an aldehyde, therefore it must be a primary alcohol.
(CH3)3C-CH2OH (CH3)3C-CHO
(CH3)2CH-CH2OH (CH3)2CH-CHO
In the given options, (b) and (c) are primary alcohols having molecular masses 88 and 74 respectively. Hence only option b is the correct option.
