In the given set of reactions :
`2-"Bromopropane " overset("alc.AgCN")underset(Delta)(to) 'X' overset(LiAIH_(4))(to) 'Y'`
The IUPAC name of product 'Y' is :

Options

A. N-methylpropanamlne
B. N-isopropylmethanamine
C. Butan-2-amine
D. N-methylpropan-2-amlne

Answer

D

Explanation

`underset"2-bromopropane"(H_3C-underset"Br"underset|CH-CH_3) underset"alc./Heat"overset"AgCN"to underset"(X) isocyanide"(H_3C-undersetunderset(NC)|CH-CH_3)`
AgCN is mainly covalent in nature and nitrogen is free to · donate electron pair fqrming isocyanide as the main product.
`{:(H_3C-CH-CH_3 overset(LiAlH_4)to H_3C-CH-CH_3),(" |" " |" ),(" "NC " "HN-CH_3),(" "X" "underset"(N-methylpropan-2-amine)"Y):}`
Nitriles on reduction with lithium aluminium hydride ( `LiAIH_4`) produce amines.
