Dehydration require an acid catyalyst to protonate the hydroxy group of the alcohol and convert it into good leaving group. Loss of water followed by a loss of a proton, given the alkene an equilibrium is established between reactants and products.
(i) To improve the yield of above reaction which of following is correct ?
Text Solution
Verified by ExpertsCHECK THE SOLUTION.
(i)
Sol.E ′ reaction favoured at high T & removal of alkene; Equilibrium reaction, forced in forward direction by removal of alkene; Lechatlier's principle.
(ii)
Sol. In 
α H = 9 and in 
α H = 10
Total α H = 19.
(iii)
Sol. Stability of carbocation formed; 
;
Resonance stabilised.
