Textbook Problem

For each pair of bonds, indicate the more polar bond, and use an arrow to show the direction of polarity in each bond.

  1. (a) C—O and C—N
  2. (b) P—Br and P—Cl
  3. (c) B—O and B—S
  4. (d) B—I and B—I

(a)

Interpretation Introduction

Interpretation: The more polar bond should be identified.

Concept Introduction:

Polar molecule: The molecule with atoms bonded with different electronegativity. Dipole moment is used to measure the polarity of the molecule.

Polarity of a molecule is measured in term of dipole moment.

Dipole moment for a polar molecule is non-zero and for a non-polar molecule dipole moment is zero

Electronegativity: The property of atom to abstract electrons towards itself making the other end positive is called electronegativity.

Explanation

For each pair of bond, indicate the more polar bond and using an arrow to show the direction of polarity in each bond.
