When attempting a Grignard reaction, you add the correct molar amount of acetone but what you didn’t know was that your lab partner also added an equimolar amount of 2,4-dimethylpentan-3-one. You used 1-bromohexane to generate the Grignard reagent and the reaction proceeded. What two products would you likely obtain (IUPAC nomenclature)? Should be products be in an equal ratio? Why or why not?

Answer:

The products formed are

2-methyl-3-isopropylnonan-3-ol and 2-methyloctan-2-ol

The products should be in equal ratio since an equipmolar amount of acetone and 2,4-dimethylpentan-3-one was initially present as reactants

Explanation:

Ketones reacts with gridnard reagents to form tertiary alcohol, and since acetone and 2,4-dimethylpentan-3-one are both ketones, gridnard reagent reduced both to tertiary alcohols:2-methyl-3-isopropylnonan-3-ol and 2-methyloctan-2-ol
