Ramu makes a detailed study on the values of electronegativity and the formation of compounds. Accordingly, he draws the following conclusion:
The larger the electronegativity (EN) difference between the combining atoms, the more ionic bonds will form.
If the EN difference is negligible, covalent bonds will form. So, which of the following values refers to covalent bonds?
P: 3.0 and 3.0
Q: 0.9 and 3.0
- Only P
- Only Q
- Both P and Q
- Neither P nor Q
Answer
Only P
Reason — The condition for the formation of a covalent bond is the electronegative difference between the combining atoms should either be zero or negligible.
P: 3.0 and 3.0, the electronegative difference is zero, leading to covalent bond formation.
Q: 0.9 and 3.0, the electronegative difference is 2.1, NO covalent bond formation.
