Answer :
Final answer:
Without the list of specific compounds, it's not possible to determine how many would not form a Grignard reagent. If cyclohexanone, acetophenone, and 2-hexanone react with methylmagnesium bromide, the expected products are tertiary alcohols. None of options is correct
Explanation:
The question is related to the formation of Grignard reagents from organic halides using magnesium (Mg) in the presence of THF (tetrahydrofuran). The specified conditions are conducive for the formation of Grignard reagents when the organic
halides are reactive enough and do not contain groups that would react with the Grignard reagent itself, such as hydroxyl (-OH) or carboxylic acid (-COOH) groups. The creation of a Grignard reagent is crucial for various synthesis reactions in organic chemistry.
To answer the first part of the question, we need to look at which compounds contain reactive groups that would impede the formation of the Grignard reagent. Given that no specific compounds were provided to evaluate, we cannot determine how many,
if any, would not form a Grignard reagent. For the second part of the question, if we react cyclohexanone, acetophenone, and 2-hexanone with methylmagnesium bromide, we will form the corresponding tertiary alcohols after a nucleophilic addition of the Grignard reagent to the carbonyl group. None of options is correct
