A) Porosity of \[A{{l}_{2}}{{O}_{3}}\]
B) Temperature
C) Concentration
D) Surface area of \[A{{l}_{2}}{{O}_{3}}\]
Correct Answer: B
Solution :
Temperature is the effective factor for dehydration of alcohol by \[A{{l}_{2}}{{O}_{3}}\] \[R-C{{H}_{2}}-C{{H}_{2}}OH\underset{{{350}^{o}}-{{380}^{o}}C}{\mathop{\xrightarrow{A{{l}_{2}}{{O}_{3}}}}}\,\] \[R-CH=C{{H}_{2}}+{{H}_{2}}O\] While at \[{{220}^{\text{o}}}-{{250}^{\text{o}}}C\] it forms ether.
