Some Basic Principles Of Organic Chemistry Question 274
Question: Which one of the following shows optical activity [NCERT 1984, 90]
Options:
A) $ HO-\underset{H}{\mathop{\underset{|}{\mathop{\overset{H}{\mathop{\overset{|}{\mathop{C}},}},}},}},-COOH $
B) $ CH_3-\underset{Cl}{\mathop{\underset{|}{\mathop{\overset{H}{\mathop{\overset{|}{\mathop{C}},}},}},}},-COOH $
C) $ CH_3-\underset{OH}{\mathop{\underset{|}{\mathop{\overset{CH_3}{\mathop{\overset{|,}{\mathop{C-,}},}},}},}},COOH $
D) $ CH_3-\underset{Cl,}{\mathop{\underset{|}{\mathop{\overset{CH_3}{\mathop{\overset{|}{\mathop{C-,}},}},}},}},COOH $
Show Answer
Answer:
Correct Answer: B
Solution:
$ CH_3-\overset{H}{\mathop{\overset{|*}{\mathop{\underset{Cl}{\mathop{\underset{|}{\mathop{C}},}}}},}},-COOH $ In this structure chiral carbon atom is present since it is optical active.
