Ethanol and Ethine Properties

The video tutorial explains a dehydration experiment where ethine gas and unreacted ethanol pass through a tube into water. Ethine is collected as a gas, while ethanol dissolves in water due to its polar nature. The tutorial discusses intermolecular forces, highlighting that ethanol forms hydrogen bonds with water, making it more soluble. In contrast, ethine, being non-polar, only has induced dipole interactions with water, leading to its collection as a gas.

What is the main observation in the dehydration experiment?

• Ethine is collected as a gas.

• Ethanol is more visible than ethine.

• Unreacted ethanol is collected as a gas.

• Ethine is collected as a liquid.

What happens to ethanol during the experiment?

• It evaporates completely.

• It remains unchanged.

• It partially converts to ethine.

• It completely converts to ethine.

Why is ethine primarily observed in the experiment?

• Ethine is more soluble in water.

• Ethanol is more soluble in water.

• Ethine reacts with water.
