Question

Mixed ionic-covalent bonds are found in
1. high strength materials
2. semiconductors
3. heat insulators
4.none of these​

Answer 1

Answer:

your answer is

4 none of these

Answer 2

Mixed ionic-covalent bonds are found in option (4) None of these

Explanation:

• Mixed ionic-covalent bonds are found in ceramic materials.
• Mixed ionic-covalent bonding is the ratio of the fraction of ionic and covalent bonds.
• This ratio relies on the difference between the electronegativities of the elements and identifies the bonding mechanisms which are dominant (Ionic or covalent bonding)
• This bond is represented by the given formula:

                         $I.F.\;=\;exp(-0.25\;\times\;\Delta E^2)$

where, $I.F$ is the fraction of ionic bonding

            $\Delta E$ is the difference between the electronegativities of the elements
