A) \[Al(OH)C{{l}_{2}}\]
B) \[A{{l}_{2}}{{O}_{3}}\]
C) \[A{{l}_{2}}C{{l}_{6}}\]
D) \[AlC{{l}_{3}}\]
Correct Answer: B
Solution :
Aqueous solution of\[AlC{{l}_{3}}\]is acidic due to hydrolysis. \[AlC{{l}_{3}}+3{{H}_{2}}OAl{{(OH)}_{3}}+3HCl\] On strongly heating\[Al{{(OH)}_{3}}\]is converted into\[A{{l}_{2}}{{O}_{3}}\] \[2Al{{(OH)}_{3}}\xrightarrow{\Delta }A{{l}_{2}}{{O}_{3}}+3{{H}_{2}}O\]
