Quote "Formaldehydes faster than > aldehydes faster than > ketones"
Are you sure about this? It says aldehydes faster than ketones, but you have a ketone as the fastest. Something not correct here.
What effect do the substituents have on the rate of hydration?
Im pretty sure
The question says 1 = slowest, 5 = fastest.
And I think I figured it out
The answers are
3-hexanone: 1 (most slowest)
2,2-difluorobutanal: 5 (most fastest)
2,2-dichlorobutanal: 4 (second most fastest)
4-chloro-2-pentanone: 2 (second most slowest)
I guess the concept is:
The carbonyl C bonded with the MOST and CLOSEST electronegative atoms will be the most reactive and have the fastest hydration rate which results in a larger Khydration
