Question: An organic compound (X) with molecular formula \(\mathrm { C } _ { 3 } \mathrm { H } _ { 6 } \mathrm...

An organic compound (X) with molecular formula C3H6O\mathrm { C } _ { 3 } \mathrm { H } _ { 6 } \mathrm { O }is not reacts oxidised. On reduction it gives C3H8O\mathrm { C } _ { 3 } \mathrm { H } _ { 8 } \mathrm { O } (Y) which reacts with HBr to give is bromide (Z which is converted to Grignard’s reagent. Grignard’s reagent reacts with (X) to give 2,3- dimethylbutan-2-ol, (X) (Y) and (Z) respectively are.

B

CH3CH2CHO,CH3CH=CH2,CH3CH(Br)CH3\mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { CHO } , \mathrm { CH } _ { 3 } \mathrm { CH } = \mathrm { CH } _ { 2 } , \mathrm { CH } _ { 3 } \mathrm { CH } ( \mathrm { Br } ) \mathrm { CH } _ { 3 }

C

CH3COCH3,CH3CH(OH)CH3,CH3CH(Br)CH3\mathrm { CH } _ { 3 } \mathrm { COCH } _ { 3 } , \mathrm { CH } _ { 3 } \mathrm { CH } ( \mathrm { OH } ) \mathrm { CH } _ { 3 } , \mathrm { CH } _ { 3 } \mathrm { CH } ( \mathrm { Br } ) \mathrm { CH } _ { 3 }

D

CH3CH2CHO,CH3CH2CH2OH,CH3CH2CH2Br\mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { CHO } , \mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { OH } , \mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { Br }

Answer

CH3COCH3,CH3CH(OH)CH3,CH3CH(Br)CH3\mathrm { CH } _ { 3 } \mathrm { COCH } _ { 3 } , \mathrm { CH } _ { 3 } \mathrm { CH } ( \mathrm { OH } ) \mathrm { CH } _ { 3 } , \mathrm { CH } _ { 3 } \mathrm { CH } ( \mathrm { Br } ) \mathrm { CH } _ { 3 }
