Why is NH3 called Lewis Alkali ?

Why is NH3 called Lewis Alkali ?
by

1 Answer

Answer :

According to the Lewis theory of acid-base, all the compounds that can give electrons to protons are called bases. The compounds containing mainly free electrons behave like Lewis alkalis. The nitrogen of NH 3 contains free pairs of electrons so it can donate a pair of electrons to protons. That is why it is called Lewis alkali.

Why NH3 has a higher boiling point than CH4 and HCl?

Description : Why NH3 has a higher boiling point than CH4 and HCl?

Last Answer : Both NH3 and HCl exhibit hydrogen bonding as intermolecularforces, whereas CH4 does not. This makes CH4 have a lower boilingpoint. Since there are 3 hydrogen atoms in NH3 and only 1 inHCl(g), the intermolecular forces would be expected to be greaterin NH3 than in HCl.
