A) \[A{{l}_{2}}{{O}_{3}}<Si{{O}_{2}}<S{{O}_{2}}<{{P}_{2}}{{O}_{3}}\]
B) \[Si{{O}_{2}}<S{{O}_{2}}<A{{l}_{2}}{{O}_{3}}<{{P}_{2}}{{O}_{3}}\]
C) \[S{{O}_{2}}<{{P}_{2}}{{O}_{3}}<Si{{O}_{2}}<A{{l}_{2}}{{O}_{3}}\]
D) \[A{{l}_{2}}{{O}_{3}}<Si{{O}_{2}}<{{P}_{2}}{{O}_{3}}<S{{O}_{2}}\]
Correct Answer: D
Solution :
With decrease in size from Al to S the basic nature of oxide decrease and acidic nature increases. \[A{{l}_{2}}{{O}_{3}}<Si{{O}_{2}}<{{P}_{2}}{{O}_{3}}<S{{O}_{2}}\] \[A{{l}_{2}}{{O}_{3}}\] is amphoteric, \[Si{{O}_{2}}\] is slightly acidic whereas \[{{P}_{2}}{{O}_{3}}\] and \[S{{O}_{2}}\] are the anhydrides of acids \[{{H}_{3}}P{{O}_{3}}\] and \[{{H}_{2}}S{{O}_{3}}\].You need to login to perform this action.
