A) 1
B) 2
C) 3
D) 4
Correct Answer: A
Solution :
Possible structures of alcohols with molecular formula \[{{C}_{4}}{{H}_{10}}O\] are \[\underset{Butan-1-ol}{\mathop{C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}OH}}\,\,\,\,\underset{\begin{smallmatrix} Butan-2-ol \\ \left( has\text{ }chiral\text{ }C-\text{ }atom \right) \end{smallmatrix}}{\mathop{C{{H}_{3}}C{{H}_{2}}-\overset{\begin{smallmatrix} C{{H}_{3}} \\ | \end{smallmatrix}}{\mathop{*CH}}\,-OH}}\,\] \[\underset{tert-Butyl\text{ }alcohol}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix} | \\ C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix} C{{H}_{3}} \\ | \end{smallmatrix}}{\mathop{C}}}\,-OH}}\,\] Thus, only one alcohol is chiral in nature.
