- D
✓
Answer
Correct option: B.
${{C}_{2}}{{H}_{5}}CHO\underset{{{H}^{+}}/{{H}_{2}}O}{\mathop{\xrightarrow{C{{H}_{3}}MgBr}}}\,$
b
(b)${{C}_{2}}{{H}_{5}}CHO\underset{{{H}^{+}}/{{H}_{2}}O}{\mathop{\xrightarrow{C{{H}_{3}}MgBr}}}\,\,\underset{\,\,\,\,\,\,C{{H}_{3}}}{\mathop{\underset{|}{\mathop{\overset{\,H}{\mathop{\overset{|}{\mathop{{{C}_{2}}{{H}_{5}}-{{C}^{*}}-OH}}\,}}\,}}\,}}\,$
(b)${{C}_{2}}{{H}_{5}}CHO\underset{{{H}^{+}}/{{H}_{2}}O}{\mathop{\xrightarrow{C{{H}_{3}}MgBr}}}\,\,\underset{\,\,\,\,\,\,C{{H}_{3}}}{\mathop{\underset{|}{\mathop{\overset{\,H}{\mathop{\overset{|}{\mathop{{{C}_{2}}{{H}_{5}}-{{C}^{*}}-OH}}\,}}\,}}\,}}\,$
