Question

142. If the difference in electronegativity between two elements is 1.7, then the bond is (1) 60% covalent 40% ionic (2) 50% covalent 50% ionic (3) 40% covalent 60% ionic (4) 70% covalent 30% ionic​

Answer 1

Answer:

If the electronegative difference is >1.7 then its nature is ionic and <1.7 then its nature is covalent and if its equal to 1.7 then nature of bond will be 50% ionic and 50% covalent.
