Write the preparation of alkene from alcoholes by acidic dehydration. |
|
Answer» Solution :Prepare : `R-OH` (alcohol) heated with conc. `H_(2)SO_(4), H_(2)O` molecule is released. Dehydration : Alcohol `(C_(n)H_(2n+1)OH`, where `n gt 1`) treated with conc. `H_(2)SO_(4), H_(2)O` molecule is released, since a WATER molecule is eliminated from the alcohol molecule is eliminated from the alcohol molecule in the presence of ACID, this reaction is known as acidic dehydrogenation of alochols.  reaction : In these reaction -OH group and `beta`-CARBON hydrogen is removed in the form of `H_(2)O` and `pi`-bond is FORMED between `alpha` and `beta`-carbon. These reaction also known as `beta`-elimination reaction. |
