Lewis structure and molecular geometry for nh2cl

Answer :

The given molecule is,

Nitrrogen has '5' valence electrons, hydrogen has '1' valence electron and chlorine has '7' valence electrons.

Therefore, the total number of valence electrons in ,

= 1(5) + 2(1) + 1(7) = 14

According to electron-dot structure, there are 6 number of bonding electrons and 8 number of non-bonding electrons.

Now we have to determine the molecular geometry of .

As, the number of electrons in  is 4. So, the hybridization will be and the electronic geometry of the given molecule will be tetrahedral.

But, as there are three atoms present around the central nitrogen atom and the fourth position will be occupied by lone pair of electrons. That means the repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be trigonal pyramidal.

The Lewis-dot structure and molecular geometry of are shown below.
