Alkenes are obtained by elimination reactions
Explanation:
Alkenes are obtained by elimination reactions Following are some examples.
- Dehydration of Alcohol
In this process alcohol is dehydrated
(1) byheating with conc.#H_2SO4 at 450K# or by#P_2O_5#
or (2) by passing alcohol vapor over heated Alumina,#Al_2O_3#
Reaction
- Dehydrohalogenation
In this process Alkyl halide except fluoride is reacted with alcoholic#KOH#
Reaction
#RCH_2CH_2X->RCH=CH_2+ HX# (where X =Cl,Br,I)
- Dehalogenation
In this process vicinal or geminal dihalide except fluoride is heated with alcoholic
Reaction
Other process like cracking of alkane is also there
