All Organic Name Reactions 11th and 12th

All Organic Name Reactions : 11th  And 12th Organic chemistry is still considered a tough subject to study and we all can agree that it is indeed volatile in nature. We ourselves have encountered that studying one reaction is easier than revising it as revision consumes a lot more time than the actual study. Organic […]

Discharge Tube

DEFINITION It is the arrangement of electrodes containing gas at lower pressure. It is the cylindrical tube in which an electrical conduction takes place. It contains two metal plates connecting on opposite sides. These plates are called cathode and anode. The discharge tube or vacuum tube was discovered by German physicist Heinrich Geissler. Significance The […]

Dipole Dipole Forces

DEFINITION It is attractive force between opposite charge of polar molecules. The polar molecule have partially a positive end and negative end. EXPLANATION The stronger the dipole moment the stronger will be dipole- dipole forces. It is stronger than dispersion forces in small molecules. When there is not equal distribution of electron in molecules they […]


DEFINITION It is a separation of equal and opposite charges preferably in a molecule or a compound with different types of atoms. There are two types of types :- i) electric dipole ii)magnetic dipole i) Electric dipole – When a positive and negative charges is separated from each other then electric dipole occur .It may […]

Dalton’s Law of Partial Pressure

EXPLANATION It states that the total pressure of mixture of gas is equal to sum of partial pressure exerted by each individual gases. MATHEMATICAL EXPLANATION It can be mathematically expressed as Ptotal =sum of (Pj) OR Ptotal=P1+P2+…..+Pn Where,Ptotal = Total pressure of mixture. P1,P2,….,Pn are partial pressure of gases. Dalton’s law of partial pressure can […]

Dipole Moment

DEFINITION Dipole Moment: The measurement of distance between two charges that are opposite to each other is called dipole movement. It can found in covalent bond and ionic bond of molecules. FORMULA Dipole moment can also define as product of charge magnitude and the distance between the center of positive and negative charge.It is denoted […]

Diffusion of Gases

DEFINITION: The spontaneous mixing of different molecules of gases by random motion to form homogeneous mixture is called diffusion of gases. Diffusion in gases is faster because the gases have large inter molecular spaces between them and hence they move very quickly in all direction. The diffusion of lighter gases is faster than the heavy […]
