Which of the following is a non polar dielectric?a)Waterb)Alcoholc)HCld)BenzeneCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

Alcohol and HCl are polar molecules since they have a net dipole moment towards a particular direction. Both water and benzene are non-polar molecules. But water is a conductor of electricity, whereas benzene is a dielectric (insulator).

Answer

D)Benzene
because Non polar dielectrics: Like N2, O2, Benzene, Methane, etc are made of non-polar atoms/molecules. In non-polar molecules, when no electric field is applied the centre of positive charge coincides with the centre of negative charge in the molecule. Each molecule has zero dipole moment in its normal state.

Answer

Benzene can't be polar...I think, due to it's resonating structure...it will loss it's stability

Answer

Reasons ...
1. made up of non- polar molecules

2. The centre of mass of +ve and -ve charge do not coincide with each other respectively

3. Have zero dipole moment ( in absence of any external field)

4. Have symmetrical shape

Answer

D

Answer

Because benzene is a hydrocarbon that contains only C-C and H-C bonds

Answer

Nonpolar dielectrics are substances that have a symmetrical distribution of charge and do not have a permanent dipole moment. They do not have a positive and negative end, resulting in zero net dipole moment.

Among the options given, benzene (option D) is a nonpolar dielectric. This is because benzene has a symmetrical hexagonal structure with carbon atoms arranged in a ring, and each carbon atom is bonded to a hydrogen atom. The carbon-hydrogen bonds have similar electronegativities, resulting in a nonpolar molecule.

Water (option A) is a polar molecule due to the presence of two hydrogen atoms bonded to an oxygen atom. The oxygen atom is more electronegative than the hydrogen atoms, creating a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms. This polarity gives water a permanent dipole moment.

Alcohol (option B) refers to a group of compounds that contain a hydroxyl (-OH) group bonded to a carbon atom. The presence of the hydroxyl group makes alcohols polar molecules. However, the polarity of alcohol can vary depending on the size and structure of the alkyl group attached to the hydroxyl group. Smaller alcohols, like methanol and ethanol, are more polar compared to larger alcohols, like octanol.

HCl (option C) is a polar molecule due to the difference in electronegativity between hydrogen and chlorine. Chlorine is more electronegative than hydrogen, resulting in a partial negative charge on the chlorine atom and a partial positive charge on the hydrogen atom. Hence, HCl has a permanent dipole moment.

In summary, among the given options, benzene (option D) is a nonpolar dielectric.
