Q. Define the Normality of solutions?
Ans. Sometime normality is used to measure concentration. Normality (abbreviated N) is the number of gram-equivalent masses of solute in 1 liter of solution. A gram-equivalent mass is the mass of acid (or base) which can give one mole of hydrogen (or hydroxide) ions.
In hydrogen spectrum the different lines of Lyman series are present is : (1 )UV field (2) IR field (3) Visible field (4) Far IR field Ans: UV field

The bond energy of an O- H bond is 109 kcal mol 1. When a mole of water is formed from H and O atoms, then 218 kcal is released. Two O-H bonds are there is H2O so 2*109 kcal an

A hypothetical molecule, X–Y, has a dipole moment of 1.48 D and a bond length of 161 pm. Calculate the percent ionic character of this molecule
Since fluorine is very electronegative as a result hydrogen develop a very positive character. As a result the H-bonding is very tough because of large difference in electronega
