A) \[{{(C{{H}_{3}})}_{3}}COH\]
B) \[{{({{C}_{2}}{{H}_{5}})}_{3}}COH\]
C) \[{{({{C}_{2}}{{H}_{5}})}_{2}}C(C{{H}_{3}})OH\]
D) \[{{(C{{H}_{3}})}_{3}}CC{{H}_{2}}OH\]
Correct Answer: D
Solution :
During alkaline\[KMn{{O}_{4}}\]oxidation brown precipitates of\[Mn{{O}_{2}}\]are formed. Out of the alcohols listed only\[{{(C{{H}_{3}})}_{3}}C-C{{H}_{2}}OH\]is\[1{}^\circ \]alcohol and hence undergoes oxidation easily. All the remaining alcohols are 3° and hence, do not under go oxidation easily. \[2KMn{{O}_{4}}+{{H}_{2}}O\xrightarrow[{}]{{}}2Mn{{O}_{2}}\text{+}2KOH\]\[+3[O]\]
