Explain the meaning of the following words :
volatility
reducing nature
acidic nature
thermal stability
Volatility is a property of substance to vaporize. Since high volatile compounds have weak intermolecular interaction, they exhibit high vapor pressure and low boiling point. Reducing nature is a characteristic...

what is meant by basicity and acidity of the compound .
how to find the basicity and acidity of the compounds?
Acidity is the ability of compound to lose hydrogen ion H+, leaving an anion behind. Acidity depends on the stability of the anion formed. The most acidic organic compound are...

can you please explain me reducing nature with example because i have studied some where that reducing nature means to liberate H+ ion .
so please clear my doubt.
According to Bronsted-lowry theory acid is a compound that can transfer proton to any other compound. As to reductants and reducing power, it is well known fact that alkaline metals...

What is difference between basicity and nucleophilicty? Discuss the structural
features which affect the basicity of a molecule.
Answer: Basicity is a thermodynamic property and Nucleophilicity is kinetic property. Basicity is the measure in which extent base can abstract the proton. If Basicity is high equilibrium will favour...

Explain how you would use the Arrhenius concept to explain the basicity of Na2CO3 and acidity of AlCl3.
Even though both compounds do not contain H+ and OH- ions, Arrhenius concept in these cases can be applied from the point that adding Na2CO3 to water increases the concentration...

Why Aniline is stronger base than Trinitro Aniline?
basicity means the ability of donating electron pair,now aniline has 1 lone pair on the N atom of NH2 group,which is stabilized by resonance in the benzene ring. So,the availability...

Aniline, C6H5NH2 is a weak base. A 0.3 M aniline solution was prepared and it was determined that the aniline had undergone 0.5% ionisation. Calculate the pH of this solution.
5% = 0.05 pH = 14 - pOH pOH = -lg(OH-) = -lg(0.3*0.05) = -lg(0.015) = 1.82 pH = 14 - 1.82 = 12.18
