Question

acidity of carbonyl compounds question

Answer 1

@imqwerty would you mind assisting? I'm thinking it's either C or E

Answer 2

option A has an active methylene group

Answer 3

this group is very acidic because of the stable conjugate ion

Answer 4

in options C and E the singly bonded oxygens will reduce the delocalization of the negative charge by interfering with their lone pairs and hence the conjugate ion would be less stable than the one in option A

Answer 5

Ah. Good to know. Thank you.
