The end product of the following sequence of reactions
The end product of the following sequence of reactions
\[OH\xrightarrow[{{H}_{2}}O]{{{K}_{2}}C{{r}_{2}}{{O}_{7}},{{H}_{2}}S{{O}_{4}}}\] \[\xrightarrow[{{H}^{+}}\text{(Cat )}]{C{{H}_{3}}OH\text{(excess )}}\,\,\,\xrightarrow[\left( \text{ii} \right)\,{{H}_{3}}{{O}^{+}}]{\left( \text{i} \right)\,2C{{H}_{3}}MgBr}\]
A.
B.
C.
D.
Answer :
Solution :
\[OH\xrightarrow[{{H}_{2}}O]{{{K}_{2}}C{{r}_{2}}{{O}_{7}},{{H}_{2}}S{{O}_{4}}}\] 
\[COOH\xrightarrow[{{H}^{+}}]{C{{H}_{3}}OH}\] 
\[COOC{{H}_{3}}\xrightarrow[\text{Excess}/{{H}_{3}}{{O}^{+}}]{C{{H}_{3}}MgBr}\] 
\[OH\xrightarrow[{{H}_{2}}O]{{{K}_{2}}C{{r}_{2}}{{O}_{7}},{{H}_{2}}S{{O}_{4}}}\] \[COOH\xrightarrow[{{H}^{+}}]{C{{H}_{3}}OH}\] \[COOC{{H}_{3}}\xrightarrow[\text{Excess}/{{H}_{3}}{{O}^{+}}]{C{{H}_{3}}MgBr}\]
