Practice question · Estimate
Two bonded atoms have electronegativities 3.0 and 2.1. Set the electronegativity difference of the bond.
Estimate on a scale from Nonpolar (0) (0) to Strongly ionic (3) (3).
Hints
- Take the difference between the two values.
- Compute 3.0 - 2.1 and place it on the scale.

Why
EN , which lands in the 0.4 to 1.7 band, a polar covalent bond, with the shared pair displaced toward the more electronegative atom but not transferred outright.
