A substitution reaction is one where one functional group replaces another. For example, the -OH group on an alcohol could be replaced by a Bromine atom from NaBr.
A generic substitution is a type of congress party that is involved with various types of congress meetings. A therapeutic substitution is a massage they give in therapy.
The 5 branches of chemistry are the analytical chemistry organic chemistry inorganic chemistry physical chemistry biochemistry
Acetylide formations are very useful inorganic chemistry reactions in combining carbon chains, particularly addition and substitution reactions.
There are many specialized branches of chemistry. Some of these branches include biochemistry, physiological chemistry, analytical chemistry, and organic chemistry.
Williamson's synthesis an example of nucleophilic substitution rxn, in this rxn an alkyl halide is allowed to react with a Na alkokide.

Is the direct displacement of atom or group of atom by atom or group of atom.

There are a few different mechanisms in organic chemistry SN1, SN2, E1, and E2. SN stands for substitution, and E stands for Elimination. The substitution mechanism is where a new bond is formed in place of a preexisting bond. Where as elimination rx is where an atom acts as a leaving group and is not replaced. the numbers denoted the amount of steps that much happen. i.e SN2 is a substitution reaction in which the leaving group first has to leave before the other group attacks the carbocation (if that is the case).
The question is probably intended to be about SN1 reaction. See the following from Wikipedia, accessed Feb. 25, 2013: "The SN1 reaction is a substitution reaction in organic chemistry. "SN" stands for nucleophilic substitution and the "1" represents the fact that the rate-determining step is unimolecular".
