# Why is ammonia a Lewis base?

Jul 18, 2018

Well what is a $\text{Lewis base...?}$

#### Explanation:

Is it not an electron pair $\text{DONOR...}$?

And of course ammonia CAN behave in this capacity...i.e. consider its Bronsted basicity..

$N {H}_{3} \left(a q\right) + {H}_{2} O \left(l\right) r i g h t \le f t h a r p \infty n s N {H}_{4}^{+} + H {O}^{-}$

The equilibrium lies to the left as we face the page. And ammonia is a potent ligand towards transitions metals...

$C o C {l}_{3} \left(a q\right) + 6 N {H}_{3} \left(a q\right) \rightarrow {\left[C o {\left(N {H}_{3}\right)}_{6}\right]}^{3 +} + 3 C {l}^{-}$

The $\text{hexamine cobalt(III)}$ species is a classic Werner compound.

And thus ammonia fits the description...still pretty smelly tho, and when you open the bottle the neighbours complain if you are a bit careless...
