Substitution
The SN reaction is a substitution reaction. An example of the SN reaction is Br. H3CH2C.
It is substitution because hydrogen of carboxylic acid is replaced by an alkyl group.
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".
by reading question carefully ,first understand the role of reagent / acids/ bases and any functional group that is given.Determine the reaction center and applied the basic knowledge of organic chemistry

A reaction in which a negative ion (nucleophile) attacks on a partially positive carbon atom then reaction is known as nucleophilic reaction, it may be substitution reaction or addition reaction.

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.

Treatment of a salt with carbon dioxide brings about substitution of carboxyl group for the hydrogen of the ring. this is known as kolbe reaction.
