Some Basic Principles Of Organic Chemistry Question 204
Question: Which is the decreasing order of stability [IIT-JEE (Screening) 1993] (i) $ CH_3-\overset{+}{\mathop{C}},H-CH_3 $ (ii) $ CH_3-\overset{+}{\mathop{C}},H-O-CH_3 $ (iii) $ CH_3-\overset{+}{\mathop{C}},H-CO-CH_3 $
Options:
A) $ (i)<(ii)<(iii) $
B) $ (i)>(ii)>(iii) $
C) $ (iii)>(ii)>(i) $
D) $ (ii)>(iii)>(i) $
Show Answer
Answer:
Correct Answer: B
Solution:
$ CH_3-\overset{,+}{\mathop{\underset{CH_3}{\mathop{\underset{|,}{\mathop{CH}},}},}}>CH_3-\underset{OCH_3}{\mathop{\underset{|,}{\overset{,+}{\mathop{CH}}},}},>CH_3-\underset{COCH_3}{\mathop{\underset{|}{\mathop{\overset{+}{\mathop{CH}},}},}}, $
