A
$ C{{H}_{3}}-\underset{\begin{smallmatrix} | \\ C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix} OH \\ | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}} $
B
$ C{{H}_{3}}-\overset{\begin{smallmatrix} OH \\ | \end{smallmatrix}}{\mathop{CH}}\,-C{{H}_{3}} $
C
$ {{(C{{H}_{3}})}_{3}}-C-C{{H}_{2}}OH $
D
none of the above
Solution:
Only $ 1{}^\circ $ alochol and $ 2{}^\circ $ alcohol react with alkaline $ KMn{{O}_{4}} $ . $ \underset{Alcohol}{\mathop{C{{H}_{3}}.\overset{\begin{smallmatrix} OH \\ | \end{smallmatrix}}{\mathop{CH}}\,.C{{H}_{3}}}}\,\xrightarrow[{}]{KMn{{O}_{4}}}\underset{Ketone}{\mathop{C{{H}_{3}}.\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,.C{{H}_{3}}}}\, $ $ \xrightarrow[{}]{[O]}\underset{Ketone}{\mathop{C{{H}_{3}}COOH}}\, $
