Question

So2 is gas while SeO2 is solid at room temperature why?​

Answer 1

Answer:

SO2 is a gas whereas SeO2 is solid. This is because SeO2 has a chain polymeric structure consisting of alternate selenium and oxygen atoms. This one dimensional chain forms strong interactions thus it exists as solid. Whereas SO2 is molecular and no such strong interactions is present between them
