Concept explainers
Interpretation:
The term used for bond ‘polar’ is to be discussed.
Concept introduction:
Electronegativity is the power of an atom to attract a shared pair of electrons.
It tells about the polarity of the bond.
Answer to Problem 7A
A bond is polar means it carriesa partial positive and negative charge.
If the electronegative difference between the atoms is intermediate, then the polar covalent bond is formed.
Explanation of Solution
A covalent bond is formed by the sharing of electrons between the atoms forming the bonds.
A polar covalent bond is formed between two different atoms.
A non-polar covalent bond is between the same two atoms.
Thus, the electronegative difference value depicts which type of bond is formed between two atoms.
For example:
The bond formed in
More electronegative atom acquires partially negative charge and less electronegative atom acquires a partial positive charge.
Thus, electronegative values are helpful in determining the polarity of the bond.
