Exercise 1

Predict major product (final product) in the given sequence of reaction

Which of the following reaction is most suitable for preparation of ${\mathrm{PhCH}}_2{\mathrm{CHOHCH}}_3$

In the following sequence of reactions

the product $\left(\mathrm{B}\right)$ is:

The sequence of three steps involved in the following conversion can be

$\mathrm{HC}\equiv \mathrm{CH}\underset{\mathrm{FeTubc}}{\overset{\mathrm{RedHot}}{\to }}\underset{\mathrm{Fe}}{\overset{{\mathrm{Br}}_2}{\to }}\mathrm{P}\stackrel{}{\left(1 \mathrm{eq}.\right)}⟷\mathrm{Q}\stackrel{ }{\underset{\mathrm{Ether}}{\overset{\mathrm{Mg}}{\to }}}\mathrm{S};\mathrm{T}⟷\mathrm{R}\underset{\mathrm{\Delta }, \mathrm{Distill}}{\overset{\mathrm{Ca}{\left(\mathrm{OH}\right)}_2}{\leftarrow }}\mathrm{R}\underset{}{\overset{{\mathrm{KMnO}}_4}{\leftarrow }}{\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH}$

$\mathrm{S}$and $\mathrm{T}$ are mixed and product is hydrolysed and heated in presence of conc. ${\mathrm{H}}_2{\mathrm{SO}}_4$ and product is ozonolysed then following is obtained.
