two atoms. The atom which donates the electron is called cation which is a positive ion whereas the atom which gains the electron is called anion which is a negative ion. The opposite charge of cation and anion attract one another due to the electrostatic force which is formed between them. The formation of a ionic bond involves a metal and a non-metal. Thus it forms the ionic bond. (A) EXAMPLE OF IONIC BOND (1) Sodium Chloride Sodium chloride is an ionic compound formed by the reaction between

Sulphonation – The Process Most electrophilic substitution reactions are irreversible but sulfonation is an exception. Treatment of benzene with "oleum" (a solution of SO3 in concentrated sulfuric acid) will give the sulfonic acid‚ the electrophilic species being sulfur trioxide which is Lewis acidic. Fig – 1 Sulphonation : Benzene equation The sulfonic acid can be converted back by treatment with hot aqueous acid. The reason for this reversibility is the fact that the Wheland intermediate is overall

Statements: C2.2: Chemical Potential Energy Potential energy is stored whenever work must be done to change the distance between two objects. The attraction between the two objects may be gravitational‚ electrostatic‚ magnetic‚ or strong force. Chemical potential energy is the result of electrostatic attractions between atoms. C3.3: Heating Impacts Heating increases the kinetic (translational‚ rotational‚ and vibrational) energy of the atoms composing elements and the molecules or ions composing compounds

quickened‚ stem and leaf development are enhanced‚ and yields are expanded. Gandhare and Patwardhan (2014) conducted a research about the Electric Field Adoption for Germination Improvement. The utilization of electrostatic field prominently affected seed germination. The adaption of electrostatic field is the best strategy for seed improvement. Because of straightforwardness‚ this method is suitable for commercialization. The voltage inclination of 2 kV/mm‚ 20-second interim is the ideal value for best
