Overall transformation : Ar-H to Ar-R
Named after Friedel and Crafts who discovered the reaction in 1877.
Reagent : normally the alkyl halide (e.g. R-Br or R-Cl) with aluminum trichloride, AlCl3, a Lewis acid catalyst.
The AlCl3 enhances the electrophilicity of the alkyl halide by complexing with the halide.
Electrophilic species : the carbocation (i.e. R +) formed by the "removal" of the halide by the Lewis acid catalyst
The reactive electrophile, the carbocation is prone to rearrangement to a more stable carbocation which will then undergo the alkylation reaction.

Friedel-Crafts reactions are limited to arenes as or more reactive than mono-halobenzenes
Other Lewis acids such as BF3, FeCl3 or ZnCl2 can also be used
Other sources of carbocations can also be used:
from loss of water from alcohols treated with acid such as H2SO4
from the protonation of alkenes by acid such as H2SO4
Alkylation products can also be obtained by the reduction of Friedel-Crafts acylation products
The thirteen colonies fought Great Britain. The war lasted 8 years. (from 1775-1783)
Answer: 13 colonies
The answer is culture shock. This is an experience a person may have as when one would move to a cultural environment that is different from her own. It also is a personal disorientation one may feel when having unfamiliar life due to a visit in new country.

Explanation:
Erick Erick-son was a Neo-Freudian who focus on the social development of the child. Adolescence is the stage of crisis and struggle. The crisis is a term that is given by Erick-son that describes the con-flict in a life span that is related to the development stages of a human being. Erick-son describes that the person who is much better in resolving their crisis will determine future personality traits. The crisis occurs with a person is in their adolescence age that called role confusion versus self identity. This is the crisis where an individual is confused about own self identity that is being accepted and fitted in the society. Thus adolescents want to know who they are and what they want from society. When an adolescent finds the answer of these question then they identify themselves and represent self to others.
