Some Basic Principles Of Organic Chemistry Question 110
Question: In the structure $ ^{1}H_3C-\underset{CH_3}{\mathop{\underset{|,}{\mathop{\overset{CH_3}{\mathop{\overset{|,}{\mathop{^{2}C-{{,}^{3}}CH_2-{{,}^{4}}CH_3}},}},}},}}, $ Which one is quarternary carbon atom
Options:
A) C - 1
B) C - 2
C) C - 3
D) C - 5
Show Answer
Answer:
Correct Answer: B
Solution:
$ ^{1}CH_3-{{,}^{2}}\underset{\begin{smallmatrix} | \\ \underset{6}{\mathop{C}},H_3 \end{smallmatrix}}{\overset{\begin{smallmatrix} \overset{5}{\mathop{C}},H_3 \\ | \end{smallmatrix}}{\mathop{C-{{,}^{3}}CH_2,}}},-,{}^{4}CH_3 $
$ C-2 $ is quaternary carbon because it is attached to 4 other carbon atoms.
