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?

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
