Predict the product of the following reaction sequence.

Question

Quizplus · Accepted Answer

The reaction sequence involves the following steps: 
Step 1: The reactant is treated with CH3MgBr, which is a Grignard reagent. Grignard reagents are known to add to carbonyl groups (C=O), resulting in the formation of alcohols (ROH). In this case, the reactant has a ketone group (C=O), which will be attacked by the Grignard reagent to give an alcohol. 
The product of this step is III, which is an alcohol.

Step 2: The alcohol product (III) is treated with H2SO4 and heat. This is a dehydration reaction, which removes a molecule of water (H2O) from the alcohol. The product of this step is II, which is an alkene.

Therefore, the overall product of the reaction sequence is II.
