Question

In the following reaction, $C_6{H}_{5}C{H}_{2}Br\stackrel{\left(ii\right)Mg,Ether}{\underset{\left(ii\right)H_3{O}^{+}}{\to }}X$. The product $X$ is:

• A. $C_6{H}_{5}C{H}_{2}OC{H}_2{C}_6{H}_5$
• B. $C_6{H}_{5}C{H}_{2}OH$
• C. $C_6{H}_{5}C{H}_3$
• D. $C_6{H}_{5}C{H}_{2}C{H}_2{C}_6{H}_5$

Answer 1

The correct option is C $C_6{H}_{5}C{H}_3$

Formation of Grigners's reagent is shown in the image $1.$

Grignards reagent is very reactive. It react with variety of inorganic and organic results. So when it react with $H_3{O}^{+}$, has been shown in image 2.
