To investigate the conduction of electric current, Ravi performed an experiment. He took different aqueous solutions or liquids (as electrolyte) and tried to pass electricity and connected the circuit with a bulb. In the presence of which of the following, will the bulb NOT glow?

Correct option is B

The correct answer is (b) Octane (1)

Key Points:

· Metals are the elements that conduct electricity, and non-metals are elements that don't conduct electricity.

·Here, given to find an aqueous solution that doesn't conduct electricity we have, Copper sulfate, Sodium chloride, and calcium chloride are metallic solutions that conduct electricity and make the bulb glow.

·But here we have Octane which has the formula $$C_8H_18$$​ which is a non-metal which doesn't conduct electricity in its aqueous state.

Information booster:

·Octane is a gasoline additive that is needed for proper functioning of modern engines.

·Octane rating is an index of a fuel's ability to resist engine knock in engines having different compression ratios, which is a characteristic of iso-octane.

· It has 18 different structural isomers.
