Base Strength

Postby Akhil Paladugu 3G » Sat Dec 08, 2018 10:14 pm

Which is the stronger base, the hypobromite ion, BrO , or morphine, C17H19O3N?

How do we justify this answer without using Kb values

BrO- is the stronger base, it is on the list of strong bases and that should be memorized. Morphine is a weak base because the hydroxide ion is attached to nitrogen and those are always weak bases.

Morphine will accept a proton on the N atom. This is a very weak base. The conjugate acid of BrO- is BrOH which is a weak acid. This suggests that BrO- is a relatively strong base, stronger than morphine

BrOH is a strong base, and thus it will naturally be stronger than most other bases.
