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. Butan–2-amine
B. N– methylpropanamine
C. N–methylpropan-2-amine
D. N-isopropylmethanamine

Answer

C

Explanation

`underset("2-bromopropane")(H_(3)C-underset(underset(Br)(|))(C)H-CH_(3)) underset("alc/Heat")overset(AgCN)rarr underset("(X) Isocyanide")(H_(3)C - underset(underset(NC)(|))CH)- CH_(3)`
AgCN is mainly covalent in nature and nitrogen is free to donate electron pair forming isocyanide as the main product
`underset(X)(H_(3)C- underset(underset(NC)(|))(CH)- CH_(3)) overset(LiAlH_(4))rarr underset(underset("N-Methylpropan-2-amine")(Y))(H_(3)C - underset(underset(HN- CH_(3))(|))(CH)- CH_(3))`
Nitriles on reduction with lithium aluminium hydride `(LiAlH_(4))` produce amines.
