If the electronegativity difference between two atoms is 2.0, the percentage covalent character of the molecule is :

Answer»

`46%`
`72%`
`54%`
`10%`

Solution :If the ELECTRONEGATIVITY difference between two ATOMS is 1.7, then the bond is 50% ionic and 50% covalent. Now, the difference is more than 1.7, it will be SLIGHTLY more ionic than 50 i.e., 46% covalent or 54% ionic.
