Chapter 12, Problem 6A

Interpretation Introduction

Interpretation:

The term electronegativity and its use need to be discussed.

Concept introduction:

Electronegativity is the power of an atom to attract shared pair of electrons towards itself.

Answer to Problem 6A

Electronegativity is the power of an atom to attract shared pair of electrons.

If electronegative difference between the atoms is zero, then pure covalent bond is formed.

If it is intermediate, then polar covalent bond is formed.

If the difference is large, ionic bond is formed.

Explanation of Solution

Ionic bonds are formed when one species donates electrons and other accepts the donated electrons.

Covalent bond is formed if electrons are shared between the atoms forming the bonds.

Polar covalent bond is formed between two different atoms.

Non-polar covalent bond is between two same atoms.

Thus, electronegative difference value depicts which type of bond is formed between two atoms.

Conclusion

Thus, electronegative values are helpful in determining the polarity of bond.
