Chapter 9: Q9-7P b (page 276)

The pkaof acetone, CH3COCH3, is 19.3. Which of the following bases is strong enough to deprotonate acetone?

(b)Na+-C鈮�CH(pkaH2O2of25)

Short Answer

Expert verified

Answer:

Yes, strong enough to deprotonate acetone due to more pkathen acetone.

Step by step solution

01

pka of acetone

pkais a number that describes the acidity of the molecule lower the value of pkastronger will be acidic and easily donate a proton and the higher the value of pkaweaker will be the acid and stronger will be the conjugate base.

Acetone has a low value of pka thenNa+-C鈮�CH

02

pka of Na+ -C≡CH

pkaofNa+-C鈮�CH is more than acetone so that Na+-C鈮�CH is the weak acid and the strong conjugate base than acetone due to the strong conjugate base Na+-C鈮�CH able to deprotonate the acetone.
