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

Reaction mechanism has been shown below

Explanation:

It is an example of nucleophilic acyl substituion reaction followed by nucleophilic addition reaction by methylmagnesium bromide.

This reaction is possible in presence of excess methyl magnesium bromide.

Here methyl group from methyl magnesium bromide first replaces Cl by nucleophilic acyl substitution through addition-ellimination mechanism. Then methyl group of methyl magnesium bromide adds onto carbonyl group through nucleophlic addition. Lastly, work up of product mixture yields 2-methyl-2-butanol.

Full mechanism has been shown below.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
