A) Conc.\[{{H}_{2}}S{{O}_{4}}/170{{\,}^{o}}C\]
B) Dil.\[{{H}_{2}}S{{O}_{4}}/100{{\,}^{o}}C\]
C) Dil.\[{{H}_{2}}S{{O}_{4}}/140{{\,}^{o}}C\]
D) Conc.\[{{H}_{2}}S{{O}_{4}}/70{{\,}^{o}}C\]
Correct Answer: A
Solution :
Dehydration of alcohol at \[160{}^\circ -170{}^\circ C\]. \[C{{H}_{3}}-C{{H}_{2}}-OH+conc.{{H}_{2}}S{{O}_{4}}\xrightarrow{{{160}^{o}}-{{170}^{o}}}\] \[C{{H}_{2}}=C{{H}_{2}}+{{H}_{2}}O\] Hence, the correct option is (a).You need to login to perform this action.
