A = CH3 — CN B = CH3 — CH2 — NH2

Q. Consider the following sequence of reaction and find the starting material.
$Cl - CN A H_{2} N i B N a N O_{2} d i l . H_{2} S O_{4} C_{2} H_{5} O H$

$C H_{3} B r$

$C H_{3} C H_{2} M g B r$

$C H_{3} M g B r$

$C H_{3} C H_{2} B r$

$A = C H_{3} — CN$
$B = C H_{3} — C H_{2} — N H_{2}$
