$C{H}_2=CH-\underset{C{H}_{2}C{H}_3}{\underset{|}{C}H-}\underset{Cl}{\underset{|}{C}}=C{H}_2$

• A. 3-Ethyl-4-chloropenta-1, 4-diene
• B. 2-Chloro-3-ethylpenta-1, 4-diene
• C. 4-Chloroethenylpent-1-ene
• D. 3-Ethenyl-4-chloropent-4-ene

Answer 1

The correct option is B 2-Chloro-3-ethylpenta-1, 4-diene

$\stackrel{5}{C}{H}_2=\stackrel{4}{C}H-\underset{C{H}_{2}C{H}_3}{\underset{|}{\stackrel{3}{C}}H-}\underset{Cl}{\underset{|}{\stackrel{2}{C}}}=\stackrel{1}{C}{H}_2$

The correct IUPAC name is 2-Chloro- 3 ethyl-penta 1,4 -diene
