Some Basic Principles Of Organic Chemistry Question 355
Question: Which of the following will have a mesoisomer also [AIEEE 2004]
Options:
A) 2, 3-Dichloropentane
B) 2, 3-Dichlorobutane
C) 2-Chlorobutane
D) 2-Hydroxypropanoic acid
Show Answer
Answer:
Correct Answer: B
Solution:
$ \underset{\text{2 chlorobutane}}{\mathop{\underset{\ \ \ CH_3}{\mathop{\underset{H\ -,\underset{|}{\mathop{C}}-,H}{\overset{\ \ \ CH_3}{\mathop{H-\underset{|}{\overset{|}{\mathop{C}}},-Cl}}},}},}}, $
$ \underset{\text{2, 3 dichlorobutane}}{\mathop{\underset{\ \ \ CH_3}{\mathop{\underset{H\ -,\underset{|}{\mathop{C}}-,Cl}{\overset{\ \ \ CH_3}{\mathop{H-\underset{|}{\overset{|}{\mathop{C}}},-Cl}}},}},}}, $
$ \underset{\text{2, 3 dichloropentane}}{\mathop{\underset{\ \ ,CH_3}{\overset{\ \ \ CH_3}{\mathop{\underset{H,-,\underset{|}{\mathop{C}}-,H}{\overset{H,-,\overset{|}{\mathop{C}}-,Cl}{\mathop{H-\underset{|}{\overset{|}{\mathop{C}}},-Cl}}},}}},}}, $
$ \underset{\text{2 hydroxy propanoic acid}}{\mathop{H_3C-\overset{OH\ \ \ \ \ \ \ }{\mathop{\underset{H}{\mathop{\underset{|}{\overset{|}{\mathop{C}}},}},-COOH}},}}, $
