intermolecular hydrogen bonding leads to association of molecules which results in raising the boiling point of liquid and the m

This occurs when the hydrogen bonding is between H-atom of one molecule and an atom of the electronegative element of another molecule. For example (i) hydrogen bond between the molecules of hydrogen fluoride..

Association of Solute Molecules - Certain solutes in solution are found to associate. This eventually leads to a decrease in the number of molecular particles in the solution. Thus, it results in a decrease in the values of observed colligative prop..

Carboxylic acids have higher boiling point than aldehydes and ketones and even alcohols of comparable masses. This is due to more extensive association of carboxylic acid molecules through intermolecular hydrogen bonding...

Association The weak electrostatic interactions of intermolecular hydrogen bonding, causes two or more molecules of a compound to exist as aggregates or associated molecules. This is seen in water molecules..

The boiling point of liquid is raised by increasing the pressure and reduced by lowering the pressure. It can be demonstrated by the apparatus shown in figure...

Cell is the structural and functional unit of life. The direction in which water flows from one cell to another cell depends on the water potential. Two factors which affect the water potential are the amount of solutes and the external pressure. Due to endosmosis protoplasm expands and ..

A dihydric alcohol, ethanediol is prepared commercially by acid hydrolysis of epoxy ethane (ethylene oxide..

Hydrogen fluoride is a low boiling liquid (boiling point 292K) while HCl, HBr and HI are gases. The anomalous property of HF is due to presence of hydrogen bonding in the molecules. Due to hydrogen bondi..

(i) Volatility - All the hydrides are volatile. The volatility increases from H 2 O to H 2 S and then decreases. This is clear from their boiling points as given belo..

Haloarenes are colorless liquids or crystalline solids. Aryl halides are heavier than water. Being heavier than water, they are insoluble in water but soluble in organic solvents. The melting and boiling points of aryl halides are nearly the same as those of..
