Dimethyl ether and ethanol have same molecular weight, but their volatilities are different-explain.

The hybridisation of oxygen in both water and diethyl ether molecules is the same but they differ in their bond angles. Explain.

Explain why the chemical properties of ortho and para-hydrogen are the same but their physical properties are different.

What do you mean by ortho and para hydrogen ? explain why the chemical properties of ortho and parahydrogen are the same but their physical properties are different.

An ether is more volatile than alcohol having the same molecular formula. This is due to:

Ethanol boils at a higher temperature than diemthyl ether, even though they have same molecular formula-explain.

The order and molecularity of an elementary reaction are the same - explain.

A solution containing 2.5 g of a non-volatile solute in 100 gm of benzene boiled at a temperature 0.42K higher than at the pure solvent boiled. What is the molecular weight of the solute? The molal elevation constant of benzene is "2.67 K kg mol"^(-1) .

Explain : HCOOH and C_2H_6OH having same molecular weight, yet boiling point of HCOOH is higher than ethanol.
