If pentan-2-one is reacted with NaBH4, followed by hydrolysis with D2O, the product will be :

A.CH3CD(OD)CH2CH2CH3

B.CH3CD(OH)CH2CH2CH3

C.CH3CH(OH)CH2CH2CH3

D.CH3CH(OD)CH2CH2CH3✓ Correct

Explanation

Pentan-2-one is the compound of five carbon atoms and the ketone group is present at the second carbon atom. So, when this compound is treated with 푁푎퐵퐻4, the ketone group will convert into alcohol group. So, when this compound is treated with 퐷2푂, the hydrogen atom of the alcohol group will be replaced with D atom. So the product will be 퐶퐻3퐶퐻(푂퐷)퐶퐻2퐶퐻2퐶퐻3.
