Draw the mechanism for the addition of methylmagnesium bromide to propanoyl chloride (ch3ch2cocl) to give 2-methyl-2-butanol.

Reaction mechanism has been given below

Explanation:

Propanoyl chloride contains an electrophilic carbonyl center to give  nucleophilic acyl substitution reaction by removing Cl group with a strong nucleophile like methylmagnesium bromide.Two equivalent of methyl magnesium bromide react with cabonyl center followed by protonation of negatively charged oxygen atom gives 2-methyl-2-butanol.In the first step, nucleophilic acyl substituion occurs. In the second step, nucleophilic addition occurs. In the third step, protonation occurs.Reaction mechanism has been shown below.

You know how the first one if filled up like the objects do the same but with the other categories
