Ionic Equations
Ionic Equations - Suppose we dissolve silver nitrate, an ionic solid in water, the ions in the crystal lattice are released and once in solution, move freely in hydrated form. The situation is represented by the equatio..
Molecule Shapes
Shapes of Molecules - such as linear, triangular, square planar, pyramidal, octahedral etc. The shape of a molecule affects its chemical and physical properties. For instance, some of the unique properties of water are due to the angular shape of its molecule (H 2 O). ..
General Properties of Ionic Compounds
Physical state Ionic compounds do not exist in the form of independent molecules but exist in the form of ions in crystalline solids, according to X-ray studies. These ions are arranged to form the crystal lattice in definite geometric ..
Polar and Non-polar Molecules
Polar and Non-polar Molecules - Polar Molecules When compounds are formed from elements whose atoms have different electronegativities, the electrons forming the bonds will have a tendency to be attracted closer to the more electronegative element. In such in..
Types of Electronegativity
When the molecule is formed by transfer of electrons (ionic bonding) the transfer takes place from electropositive atom to electronegative atom (Fig. 2.4). In the example below, Na is electropositive and Cl is electronegative. ..

The electrostatic force of attraction between the hydrogen atom of one molecule and more electronegative atom of the same or another molecule, is called hydrogen bond. When hydrogen atom gets bonded to atoms of highly electronegative elements such as fluorine, ox..
Importance of dipole moment and problems
The measurement of dipole moment helps in distinguishing between polar and non-polar molecules. Non-polar molecules have zero dipole moment while polar molecules have some value of dipole moment. For example: Non-polar molecules: O 2 , Cl 2 , BF 3 , CH 4 ..
Addition Polymerization
When the molecules of same monomer or different monomers simply add together to form a polymer,the process is called addition polymerization. The monomers commonly used are unsaturated compounds such as alkenes, alkadienes and their derivatives. This mode of polymerization can t..

Geometry of SF
6 molecule The geometry of SF 6 molecule can be explained on the basis of sp 3 d 2 Hybridization. In SF 6 the central sulphur atom has the ground state configuration, 3s 2 3p 4 as shown in fig.1.27 (a)...
