Carboxylic Acids and their Derivatives 2 Question 44
44. Predict the major product in the following reaction :
$$ \mathrm{C}{6} \mathrm{H}{5}-\mathrm{CH}{2} \mathrm{COCH}{3} \xrightarrow[\text { (ii) } \mathrm{H}^{+}]{\text {(i) } \mathrm{CH}_{3} \mathrm{MgBr} \text { (excess) }} $$
$(1994,1 M)$
Show Answer
Solution:
- $\mathrm{C}{6} \mathrm{H}{5} \mathrm{CH}{2}-\mathrm{C}-\mathrm{CH}{3} \xrightarrow[\text { (ii) } \mathrm{H}^{+}]{\text {(i) } \mathrm{CH}{3} \mathrm{MgBr}} \mathrm{C}{6} \mathrm{H}{5}-\mathrm{CH}{2}-\underset{\mathrm{CH}{3}}{\stackrel{\mathrm{C}}{\mathrm{C}}}-\mathrm{CH}{3}$
