Question

Which of the following compound give racemic mixture on nucleophilic substitution?

(a) $C{H}_3-\underset{C_2{H}_5}{\underset{|}{CH}}-Br$

(b) $C{H}_3-\underset{C_2{H}_5}{\underset{|}{\stackrel{Br}{\stackrel{|}{C}}}}-C{H}_3$

(c) $C_2{H}_5-\underset{C_2{H}_5}{\underset{|}{CH}}-C{H}_{2}Br$

• A. (a)
• B. (a),(b),(c)
• C. (b),(c)
• D. (a)(c)

Answer 1

The correct option is A (a)

It has chiral centre upon neucliophilic substitution it gives Racemic mixture.

$H_{3}C-\underset{C_2{H}_5}{\underset{|}{\stackrel{\ast }{C}}}H-Br$
