CH3- overset beginsmallmatrix O | | endsmallmatrix mathopC -O-C2H5+ underset(excess) mathopC2H5MgBr xrightarrow CH3- underset beginsmallmatrix | C2H5 endsmallmatrix overset beginsmallmatrix C2H5 | endsmallmatrix mathopC -OH When esters react with excess of Grignard reagent, 3° alcohol is formed.

Q. $C H_{3} COO C_{2} H_{5}$ with excess of $C_{2} H_{5} M g B r$ and hydrolysis gives

$C H_{3} - ∣ C_{2} H_{5} C = O$

$C H_{3} - ∣ C_{2} H_{5} C C_{2} H_{5} ∣ - O H$

$C H_{3} - ∣ C H_{3} C =$

$C H_{3} - ∣ C H_{3} C C_{2} H_{5} ∣ - O H$

$C H_{3} - C O ∣ ∣ - O - C_{2} H_{5} + (e x cess) C_{2} H_{5} M g B r$ $C H_{3} - ∣ C_{2} H_{5} C C_{2} H_{5} ∣ - O H$ When esters react with excess of Grignard reagent, $3^{\circ}$ alcohol is formed.
