This is a type of reaction mechanism that is seen in case of nucleophillic substitution reactions. It is BIMOLECULAR NUCLEOPHILLIC SUBSTITUTION mechanism. In this kind of mechanism two molecules decide the rate of reaction, so it is BIMOLECULAR mechanism. The whole mechanism proceeds through a single step. That concerted step involves the bond breaking and
It is a type of condensation reaction that involves the condensation of an aldehyde or ketone with succinic ester in the presence of sodium ethoxide or Potassium ethoxide to yield unsaturated ester acid . The complete reaction is as below. The mechanism involves 3 steps , and firstly the succinate is treated with base to
Chlorobenzene and bromobenzene can be prepared by treating bezenediazonium chloride with cuprous chloride or cuprous bromide. This reaction is also called Sandmeyer’s reaction.
It states that for a solution of volatile components, the partial vapour pressure of each component is directly proportion to the mole fraction of the component in the solution.
Thomson’s model of an atom Thomson proposed the model of an atom to be similar to that of the Christmas pudding. Thomson proposed that An atom consists of a positively charged sphere and electrons are embedded into it. The negative and positive charges are equal in magnitude so the atom as a whole is electrically
Dalton’s Atomic Theory In 1808 John Dalton published a new system of chemical philosophy in which he propose the following theory :- Matter consist of indivisible atoms. All the atoms of a given element have identical properties. Compounds are formed when atoms of different elements combined in a fixed ratio. Chemical reactions only involve the
