Question

I dont underatnd these answers.

For i: i thought the aldehyde reacts faster because it is has weaker EDG ( has H while other one has CH3), and thus is less stable

for iii: i thiugh the butanone is a faster reacter because because it has a EWG connected to it, while the acetome does not.

I. (15 pts) A. (9 pts) In each of the following pairs, circle the compound, which reacts faster or has the larger (more favorable) equilibrium constant for the indicated reaction OCH2CH3 H cid-catalyzed hydrolysis OCH2CH3 H3CH2 why?? equilibrium constant 3 r hydration 3 3 aceto 3,3-dimethyl-2-butanone equilibrium constant

Explanation / Answer

A)

I. 2nd(ketone derivative) is reacts faster than one,because on protonation of ethoxide O-atom,followed by breaking of C-O bon generates stable tertiary type carbocation having 2-ch3 groups and 1 -OCHCH3 group.

ii. 2nd one if faster than one, because presence of two cabonyl carbons increases the eelctrophilic nature,so that H2O (nucleophile) attacks easily.

iii. acetone is more reactive than butanone, because nucleophile(H2O) approaches carbony carbon easily due to less steric hindrance,but not in butanone product.
