The compound that reacts with O\[{{C}_{2}}{{H}_{4}},S{{O}_{2}},C{{l}_{2}}\] to yield methane as one of the products is

A)  \[C{{H}_{3}}CHO\]                         

B)  \[C{{H}_{3}}COC{{H}_{3}}\]

C)  \[C{{H}_{3}}COOC{{H}_{3}}\]    

D)  \[C{{H}_{3}}C{{H}_{2}}OH\]

Correct Answer: D

Solution :

                 Grignard reagent \[(C{{H}_{3}}MgBr)\] reacts with       active hydrogen (the hydrogen attached on O,         N, F or triple bonded carbon atoms)  containing compound, to give alkane. \[\underset{\text{Grignard}\,\text{reagent}}{\mathop{C{{H}_{3}}MgBr}}\,+\underset{\text{ethyl}\,\,\text{alcohol}}{\mathop{C{{H}_{3}}C{{H}_{2}}OH}}\,\xrightarrow{{}}\underset{(methane)}{\mathop{C{{H}_{4}}}}\,+\]
