Read the following statements and choose the statement which is not correct:
Ammonia is a blue coloured gas.
Ammonia has a very high melting point due to the H -Bond present in it.
The structure of ammonia is trigonal bipyramidal.
The ammonia molecule is a Lewis base.
Answers (1)
Option 1) is incorrect because ammonia is a colourless gas along with a pungent smell. So option 1) is incorrect.
Option 2 is correct because Ammonia has hydrogen bonds just as in the case of water. That is why Ammonia has higher melting and boiling point than expected on the basis of its molecular mass. So option 2 is correct.
Option 3 is correct because ammonia has a trigonal bipyramidal structure with nitrogen at its apex. It has three Bond pairs and one lone pair of electrons in its structure. so option 3 is correct
Option 4 is correct because lone pairs of electrons are present on the nitrogen of the Ammonium molecule that is why it is a Lewis base. It can donate the electrons and form the bond with the metal so option 4 is correct.
