Current Question (ID: 8008)

Question:

The molecule/s that will have non zero dipole moments is /are :

Options:

1. 1,2-dichloro benzene.
2. Cis-3-hexene.
3. Trans-2-pentene.
4. All of the above. (Correct)

Solution:

$\text{HINT: Symmetrical molecules have zero-dipole moment.} \text{Explanation:} \text{STEP 1:} \text{A dipole moment is simply the measure of net polarity in a molecule. Polar molecules exhibit a large difference in electrical charge (a positive end and a negative end), otherwise known as a dipole moment.} \text{STEP 2.} \text{Trans-2-pentene is not symmetrical around the double bond. So, it has some dipole moment. Also other molecules are not symmetrical, so all will have net dipole moment.}
