Question

What is the end product in the following sequence of reactions?
$C_2{H}_{5}N{H}_2\stackrel{\mathrm{HNO}{}_2}{\to }A\stackrel{\mathrm{PCl}{}_5}{\to }B\stackrel{\mathrm{NH}{}_3}{\to }C$

• A. Ethyl cyanide
• B. Ethyl amine
• C. Methyl amine
• D. Acetamide

Answer 1

Answer: (B)

$C_2{H}_{5}N{H}_2\stackrel{\mathrm{HNO}{}_2}{\to }{C}_2{H}_5-OH\stackrel{\mathrm{PCl}{}_5}{\to }C{H}_3-C{H}_2-Cl\stackrel{\mathrm{NH}{}_3}{\to }{C}_2{H}_{5}N{H}_2$(Ethyl amine)
