Neet Solved Paper 2013 Question 36
Question: The structure of isobutyl group in an organic compound is
Options:
A) 
B) $ C{H_3}\text{-}\underset{|}{\mathop{CH}},\text{-C}{H_2}\text{-C}{H_3} $
C) $ CH _3-CH _2-CH _2-CH _2- $
D) $ C{H_3}\text{-}\underset{\begin{smallmatrix} | \\ C{H_3} \end{smallmatrix}}{\overset{\begin{smallmatrix} C{H_3} \\ | \end{smallmatrix}}{\mathop{C}}},\text{-} $
Show Answer
Answer:
Correct Answer: A
Solution:
- iso mean one $ Me $ group is present in six chain. Hence, the structure of is o-butyl group in an organic compound is $ C{H_3}-\underset{\begin{smallmatrix} | \\ H \end{smallmatrix}}{\overset{\begin{smallmatrix} C{H_3} \\ | \end{smallmatrix}}{\mathop{C}}},-C{H_2}- $ (yl suffix is used to represent one ?H less than the parent hydrocarbon.)
