Question
Separate the following compounds into three categories - ionic, polar and covalent compounds; $N_2, NH_4Cl, NH_3, NO, NH_4NO_3, NCl_3.$
✓

Answer

Ionic compounds $= NO, NH_4Cl, NH_4NO_3$​​​​​​​
Covalent compounds $= N_2, NH_3, NO$
Polar compounds $= NCl_3​​​​​​​$​​​​​​​
Concept Insight : Electro negativity difference between the bonded atoms determines the ease of transfer of electrons between the atoms. On the basis of extent of transfer of electrons between the two atoms the bond will be ionic, covalent or polar.
