Which acid has the smallest Ka?_________
electron pair donor
b.proton donor
c.proton acceptor
d.electron pair acceptor
Explanation / Answer
1 ) electron pair acceptor is lewis acid
2) acetic acid is a stronger acid than methanol becuase of resonance
3) phenol almost completely deprotinated by NaOH
4) smallest Ka is for ethanol
explanation :
>: electron pair acceptor lewis acid and electron pair donar lewis base
>: in CH3COOH resonance is present in alcohol there is no such type resonance.
> : phenol is stronger acid among all . so it can be greatly react with NaOH
> : ethanol is the weakest acid so smallet Ka.
Ka value is more for phenol
