Question

Why is butylamine stronger base than ammonia

Answer 1

this  is   due  to  the  difference  in  electron  density. Butylamine  has  more   electron  density  than  ammonia.  Due   to  this   reason is  a  Butylamine    stronger  base than ammonia. BUtylamine  has  positive  induction  effect  of  -CH3  group  electron  density  on  N  atom  which  increases

Answer 2

Answer:

Kb of butylamine is higher than the Kb of ammonia.

Explanation:

Hello,

In this case, we can cite the methylamine and ethylamine Kb values as 4.38e-4 and 5.6e-4 respectively. On the other hand, ammonia has a Kb of 1.8e-5. Kb is important because it is a measure of how dissociated a base is; now as it is seen, Kb of ammonia is smaller than Kb of both methylamine and ethylamine, it means that the amine are more likely to dissociate, so they are stronger. Nevertheless, since the Kb are given for the aforesaid amines, one expects  the Kb of butylamine to be higher than those. Thus, butylamine is stronger than ammonia in terms of dissociation.

Best regards.
