Which one of the following has the lowest % ionic character?
Correct answer: C. BeCl2
- A. CCl4
- B. BCl3
- C. BeCl2
- D. LiCl
- E. HCl
Explanation
Electronegativity increases as we go from left to right in a period. So, the electronegativity difference between elements and chlorine decreases. Ionic character decreases with a decrease in the value of electronegativity difference between elements. thus the correct order is: CCl4<BCl3<BeCl2<LiCl.

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.
