Chapter 15, Problem 8RAT

To determine

Of the two substances, the one which contains molecules of $\text{S=C=O}$ and the one which contains molecules of $\text{O=C=O}$, the substance with higher boiling point has to be identified and the correct reason has to be chosen from the following options –

1. (a) The molecule on the left, $\text{SCO}$ because it comes later in the periodic table.
2. (b) The molecule on the left, $\text{SCO}$ because it is less symmetrical.
3. (c) The molecule on the left, $\text{OCO}$ because it is more symmetrical.
4. (d) The molecule on the right, $\text{OCO}$ because it has more mass.
