Prepare alkene from alkylhalide (dehydrohalogenation). Explain its detail. |
|
Answer» Solution :Preparation : Alkyl halide (RX) heated with potassium hydroxide is dissolued in ethanol liquid) gives, `beta`-elimination REACTION. Form of Reaction : In these reaction, from alkyl halide, halide releases in the form of ACID and alkene is formed, these is known as elimination reaction. Halogen and hydrogen is removed form `beta`-carbon and HX is released. Therefore the reaction is CALLED `beta`-elimination of alky halide. general reaction :   Rate of reaction : (i) Rate of reaction depends on the NATURE of halogen `I gt Br gt Cl`. (ii) Rate of reaction also depends on alkyl groups. Series of alkyl rate of reaction. `3^(@) gt 2^(@)1^(@)`. |
