(a ) Carbon dioxide is non -polar while water is polar. What conclusion do you draw about their structure from for this fact ?
(b) Classify the following compounds into acidic basic and amphoteric oxides . `AI_(2) O_(3),CI_(2)O_(7)` .

Text Solution

Verified by Experts

(a ) `Ooverset rarr =Coversetrarr = O` is linear bond moments are equal and opposite net dipole moment is zero. Water is a bent molecule it has a net dipole moment .

( b) `AI_(2)O_(3)` is amphoteric where as `CI_(2) O_(7)` is an acidic oxide.
