A) \[C{{H}_{3}}C{{H}_{2}}MgBr+C{{H}_{3}}COC{{H}_{2}}C{{H}_{3}}\]
B) \[C{{H}_{3}}MgBr+C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}COC{{H}_{2}}C{{H}_{3}}\]
C) \[C{{H}_{3}}C{{H}_{2}}MgBr+C{{H}_{3}}C{{H}_{2}}COC{{H}_{2}}C{{H}_{3}}\]
D) \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}MgBr+C{{H}_{3}}COC{{H}_{2}}C{{H}_{3}}\]
Correct Answer: C
Solution :
[c] First write down the structure of the required compound, observe the nature of functional group, \[C{{H}_{3}}C{{H}_{2}}-\underset{OH}{\overset{{{C}_{2}}{{H}_{5}}}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-C{{H}_{2}}C{{H}_{3}}\] and review the memory for preparing the required functional group. Here the required compound is a \[3{}^\circ \] alcohol having three ethyl groups, so only combination given in option c will introduce three ethyl groups. \[C{{H}_{3}}C{{H}_{2}}MgBr+C{{H}_{3}}C{{H}_{2}}COC{{H}_{2}}C{{H}_{3}}\xrightarrow{{}}\] \[C{{H}_{3}}C{{H}_{2}}\underset{OH}{\overset{C{{H}_{2}}C{{H}_{3}}}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,C{{H}_{2}}C{{H}_{3}}\]You need to login to perform this action.
