Solutions

Expert Solution

(a) the SiSi bond in Cl3SiSiCl3

Answer= Non polar covalent Bond

Reason: same element so same elctronegativity.

b) the SiCl bond in Cl3SiSiCl3

Answer= covalent bond

Reason:Electronegativity diference is only 1.26. For polar covalent it must must be 1.4.

c) the CaF bond in CaF2

Answer: Ionic, formation of cation and anion

d) NH bond in NH3

Answer = polar covalent ,

Reason= electronegativity difference > 1.4
