Question

Which of the following has the highest dipole moment?
(a)H
C = O
H
(b) CH₃ H
| |
C = C
| |
CH₃ H
(c) H CH₃
| |
C = C
| |
CH₃ H
(d) Cl CH₃
| |
C = C
| |
CH₃ Cl

Answer 1

Answer:

i think answer will be Cl CH3

Answer 2

The compound with highest dipole momentum is :

(d) Cl CH₃

CH₃ Cl

• Dipole moment- The product of magnitude of the charges and distance between the dipoles.
• Dipole moment of the geometrical isomer compounds depends on the structure of the compounds.
• The compounds having plane of symmetry, centre of symmetry cancels out the dipole moment of the compound.
• When we see the options below, we see option a), b) have plane of symmetry. So, they dont have dipole moment.
• Now, between c and d we see Cl has greater electronegativity than H and Carbon.
• this implies that the option d) has highest Dipole moment.
