Similarity of sulfur molecule and sulfur dioxide molecule?
The similarity of sulfur molecule and the sulfur dioxide molecule is the type of bond.
Is sulphur dioxide the same as sulphur?
No, sulfur is an element and sulfur dioxide is a gaseous compound. Sulfur dioxide is the combustion product of sulfur in an oxygen atmosphere (S+O2 --> SO2) Where sulfur is an element, sulfur dioxide is a compound and where sulfur is an insoluble yellow solid, sulfur dioxide is a colorless soluble gas.
Why is sulfur dioxide polar and carbon dioxide non-polar when both have polar covalent bond?
Sulfur dioxide O - S - 0 has two valence pairs on one side of the sulfur, so the oxygens are bent downwards, making it a polar molecule (the bends make it asymmetric) Meanwhile, Carbon dioxide, O=C=O has only double bonds around the central atom, no unbonded pairs, so it is a linear, and therefore non-polar molecule. (It is symmetric)
