The major product formed in the following reaction:
Show Hint
In reactions involving nucleophilic substitution and heating, ensure that the proper addition or elimination of groups follows basic principles of organic chemistry.
The given reaction shows the reaction of a cyano group (\( \text{CN} \)) with a methyl group attached to a silicon (Si) atom, with heating (\( \Delta \)) followed by treatment with aqueous acid.
The reaction leads to the formation of the major product where a nitrile group (\( \text{CN} \)) is added in the final product.
Final Answer:
\[
\boxed{\text{C}_6\text{H}_5\text{CN}}.
\]
