Find the chemical bond in MgCl2 and CH4b...

Find the chemical bond in `MgCl_2` and `CH_4`based on the electronegativity values. Justify your answer.
(Hint: Electronegativity : Mg 1.31, Cl=3.16, C=2.55, H=2.2)

Text Solution

Verified by Experts

a) .MgCl_2. = 3.16-1.31=1.85 > 1.7
implies Ionic bond
b) .CH_4. = 2.55-2.2 = 0.35<1.7
implies Covalent Bond
