A) \[C{{H}_{3}}-\overset{O}{\mathop{\overset{\mathbf{||}}{\mathop{C}}\,}}\,-O{{C}_{2}}{{H}_{5}}\]
B) \[{{C}_{2}}{{H}_{6}}\]
C) \[{{C}_{2}}{{H}_{4}}\]
D) \[{{C}_{2}}{{H}_{2}}\]
Correct Answer: C
Solution :
Ethyl alcohol on dehydration with cone \[{{H}_{2}}S{{O}_{4}}\] at \[170{}^\circ C,\]gives ethylene. \[C{{H}_{3}}C{{H}_{2}}OH\xrightarrow[conc.\,{{H}_{2}}S{{O}_{4}}]{170{}^\circ C}\underset{\text{ethylene}}{\mathop{C{{H}_{2}}=C{{H}_{2}}}}\,+{{H}_{2}}O\]
