Which compound is most likely to contain ionic bonds? which compound is most likely to contain ionic bonds? mgf2 ch4 n2o?

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

                Less than 0.4 then it is Non Polar Covalent

                Between 0.4 and 1.7 then it is Polar Covalent 

                Greater than 1.7 then it is Ionic

For MgF₂,

                    E.N of Fluorine              =   3.98

                    E.N of Magnesium        =   1.31

                    E.N Difference                    2.67          (IONIC Bond)

For CH₄,

                    E.N of Carbon            =   2.55

                    E.N of Hydrogen        =   2.20

                    E.N Difference                 0.35     (Non-Polar Covalent Bond)

For N₂O,

                    E.N of Oxygen        =   3.44

                    E.N of Nitrogen       =   3.04

                    E.N Difference              0.40          (Non-Polar Covalent Bond)

Result:

          MgF₂ contains Ionic Bond.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
