If the difference between electronegativity values between two atoms is less than 1.7 , the bond is necessarily:
Correct answer: B. Covalent
- A. Ionic
- B. Covalent
- C. Electrovalent
- D. Polar
- E. Non - polar
Explanation
If the electronegative difference is >1.7 then its nature is ionic and <1.7 then its nature is covalent and if its equal to 1.7 then nature of bond will be 50% ionic and 50% covalent. As here, it is less than 1.7, nature is covalent.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
