Chapter 2: Q30E (page 59)

Which of the following molecules has a dipole moment? Indicate the expected direction of each.

Short Answer

Expert verified

Following molecules have a dipole moment

Direction of dipole moment

Step by step solution

01

Dipole moment

The dipole moment is a measure of the separation of two electrical charges.

Dipole moment μis a product of charge and distance between two opposite charges.

μ=q×d

02

Direction of dipole moment

The direction of the dipole moment is from the less electronegative toward the more electronegative element.

03

Step 3(a) : Dipole moment and its direction for molecule (a)

Molecule a possess dipole moment and its direction is as shown below

04

Step 3(b): Dipole moment and its direction for molecule (b)

Molecule a possess dipole moment and its direction is as shown below

05

Step 3(c): Dipole moment and its direction for molecule (c)

Molecule a possess dipole moment and its direction is as shown below

06

Step 3(d): Dipole moment and its direction for molecule (d)

Molecule a possess dipole moment and its direction is as shown below

For this molecule the resultant dipole moment is zero as the opposite dipole moment cancels each other.
