A.
2 - bromohexane \[\xrightarrow[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}]{Mg}\,\,\,\xrightarrow[\left( ii \right)\,{{H}_{3}}{{O}^{+}}]{\left( i \right)\,{{H}_{2}}C=O}\]
B.
2 - bromopentane \[\xrightarrow[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}]{Mg}\] 
C.
3 - bromopentane \[\xrightarrow[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}]{Mg}\,\,\,\xrightarrow[\left( ii \right)\,{{H}_{3}}{{O}^{+}}]{\left( i \right)\,C{{H}_{3}}CH=O}\]
D.
1 - bromobutane \[\xrightarrow[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}]{Mg}\,\,\,\xrightarrow[\left( ii \right)\,{{H}_{3}}{{O}^{+}}]{\left( i \right)\,C{{H}_{3}}COC{{H}_{3}}}\]
Answer :
