Which of the following is not a property of sulfur dioxide?(a) Colorless(b) Bent molecule(c) Odorless(d) Polar moleculeThis question was addressed to me by my school principal while I was bunking the class.My question is from P-Block Elements topic in section P-Block Elements of Chemistry – Class 12

Answer»

Right choice is (c) Odorless

To explain I would say: Sulfur dioxide has a very NASTY, pungent and SHARP smell. It is a choking gas, released when sulfur compounds are burned in excess oxygen. It is a colorless gas and bears a BENT shape with polarity DUE to the electronegativity of the oxygen atom. The structural FORMULA is ^–O – S = O.
