Proper answers only.
Please include proof
Thank you :)

Answer 1

$\huge\sf{Answer}$

The conjugate acid of (a) is water which has a pKa = 15.7. The conjugate acid of (b) is NH4+ which has a pKa = 9. Therefore, (b) has the more acidic conjugate acid and is the weaker base. ANSWER: The lone pairs on oxygen (a) are the most basic.
