2nd Sem. Chemistry Important Questions with Ans.

Que:- What is hydrogen bonding?

Ans Hydrogen Bonding: Attractive force between hydrogen atom of one molecule with strongly electronegative atom of other molecule.
● Electronegative atom posses lone pair of electrons such as, nitrogen , fluorine ,and oxygen.● Hydrogen atom interacts with strongly electronegative atom has partial positive charge on one side and partial negative charge on other side.
●Hydrogen is positive charge molecule interacts with negative charge of another molecule to form a bridge b/w the two molecules.

Que1:- Explain why p-nitrophenol is more soluble than o-nitro  phenol in water.

Ans:- In p- nitro phenol intermolecular hydrogen bond form with water molecule and in o-nitrophenol there is no possible intersection of hydrogen bond formation with water molecule hence p-nitrophenol is more soluble than o-nitrophenol.

Que:-2 Explain acetone is more volatile than alcohol.

Ans: Alcohol have strong hydrogen bonding b/w each other which makes it harder to vapourize . In acetone , weak Vander Waal’s forces exist b/w atoms and it boils at very low temperature hence acetone is more volatile than alcohol.
