Question
The compound with highest net dipole moment is ______
The compound with highest net dipole moment is ______
Open in App
Solution
The correct option is A
Option (d) is a trans isomer and thus, zero net dipole moment.
Option (b) is also a trans isomer and thus, net zero dipole moment
Among options (a) and (c), O is more electronegative when compared to −CH3 group.
Thus,
has more net dipole moment.
In option C, the 4 dipole moments are present as shown above.
The opposite directed dipole moments finally result in lower net dipole moment because of subtraction.
Formaldehyde (option d) is shown below,
The individual dipole moments add up.
Thus, in formaldehyde, maximum dipole moment is observed.
Option (d) is a trans isomer and thus, zero net dipole moment.
Option (b) is also a trans isomer and thus, net zero dipole moment
Among options (a) and (c), O is more electronegative when compared to −CH3 group.
Thus,has more net dipole moment.
