\[X\xleftarrow[{{H}_{2}}S{{O}_{4}}.{{H}_{2}}O]{HgS{{O}_{4}}}1-pentyne\xrightarrow[O{{H}^{-}},{{H}_{2}}{{O}_{2}}]{B{{H}_{3}}.THF}Y\] X and Y cannot be distinguished by

A)  Silver mirror test        

B)  iodoform test

C)  \[N{{H}_{2}}OH\]         

D)  \[LiAl{{H}_{4}}\]

Correct Answer: C

Solution :

Aldehyde and ketone can be distinguished by silver mirror test, iodoform test and \[LiAl{{H}_{4}}\]. These cannot be distinguished by \[N{{H}_{4}}OH\] (both give oximes)
