(i)\[HOC{{H}_{2}}C{{H}_{2}}OH,\] |
(ii) \[C{{H}_{3}}CHOHCHOHC{{H}_{3}}\] |
(iii) \[{{(C{{H}_{3}})}_{2}}COHCOH{{(C{{H}_{3}})}_{2}}\] |
A) I > II > III
B) II > I > III
C) III > II > I
D) I > III = II
Correct Answer: A
Solution :
Rate of oxidation depends upon steric hinderance. Greater the steric hinderance the slower is the oxidation. Thus, the correct order is \[\underset{(i)}{\mathop{\underset{C{{H}_{2}}OH}{\mathop{\underset{|}{\mathop{C{{H}_{2}}OH}}\,}}\,>\,}}\,\,\,\,\underset{(ii)}{\mathop{\underset{C{{H}_{3}}CHOH}{\mathop{\,\underset{|}{\mathop{C{{H}_{3}}CHOH}}\,}}\,}}\,>\,\underset{(iii)}{\mathop{\underset{{{(C{{H}_{3}})}_{2}}COH}{\mathop{\underset{|}{\mathop{\,\,\,{{(C{{H}_{3}})}_{2}}COH}}\,}}\,}}\,\]You need to login to perform this action.
