Some Basic Principles Of Organic Chemistry Question 154
Question: Among the following compounds which can be dehydrated very easily is [AIEEE 2004]
Options:
A) $ CH_3-CH_2-\underset{OH\ \ \ \ \ \ }{\overset{CH_3\ \ \ \ }{\mathop{\underset{|}{\overset{|}{\mathop{C}}},-CH_2}}},-CH_3 $
B) $ CH_3-CH_2-CH_2-\overset{OH}{\mathop{\overset{|}{\mathop{C}},H}},-CH_3 $
C) $ CH_3-CH_2-CH_2-CH_2-CH_2-OH $
D) $ CH_3-CH_2-\underset{CH_3\ }{\mathop{\underset{|}{\mathop{C}},H-}},CH_2-CH_2-OH $
Show Answer
Answer:
Correct Answer: A
Solution:
$ CH_3-CH_2-\underset{OH\ \ \ \ \ \ \ }{\overset{CH_3\ \ \ \ \ }{\mathop{\underset{|}{\overset{|}{\mathop{C}}},-CH_2}}},-CH_3\xrightarrow{{H^{+}}} $
$ CH_3-CH_2-\overset{CH_3\ \ \ \ ,}{\mathop{\underset{\oplus }{\overset{|}{\mathop{C}}},-CH_2}},-CH_3 $ The more stable carbocation is generated thus more easily it will be dehydrated.
