Chemistry Question on Hydrocarbons
Which statement best explains why A is more acidic than B?
A
The larger size of ketone group helps to stabilize the conjugate base
B
The ketone group exert a large inductive effect in conjugate base of A
C
The ketone group allows for resonance delocalisation of the charge in conjugate base
D
The OH oxygen in A is more electronegative than the OH oxygen in B
Answer
The ketone group allows for resonance delocalisation of the charge in conjugate base
Explanation
Solution
Compound A is more acidic than B because of the delocalisation of the charge in its conjugate base due to resonance.
