Complete the following chemical reaction : C3H7OH→170oCConc.H2SO4(X)→Br2(Y)→ExcessofalcoholicKOH(Z)
Completing the reaction:
Step 1: Dehydration reaction
Step 2: Reaction with bromine
Step 3: Reaction with an excess of alcoholic KOH
Therefore, the complete reaction is given by:
C3H7OH→170oCConc.H2SO4CH3CH=CH2→Br2CH3CH(Br)—CH2(Br)→ExcessofalcoholicKOHCH3C≡CH
27. A non-metallic element is converted into a compound X after a series of reactions. A little amount of X when tested with blue litmus turns to red. X on complete reaction with another compound Y gave the product which did not respond to litmus test. Identify the correct sequence of the reactions.
(1) 2SO2+O2→2SO3
(2) H2SO4+2KOH→K2SO4+2H2O
(3)SO3+H2O→H2SO4
(4)S+O2→SO2
