Question:

Why do different substances have different odors?

Answers

Substances generate a smell when their molecules land on so-called olfactory neurones in our noses (which, for some things, is a pretty unpleasant thought). ... But this fails to explain why some molecules with similar shapes can smell completely different, while others with quite different shapes can have a similar scent.

Explanation:

I took chemistry


The boiling point and melting point of  substances is determined by their molecular weight and the cohesion (stickiness) of the individual molecules in the substance.

Based on the cohesive molecule - molecule interactions of a substance, it may have either a high melting and boiling point or vice versa. The stronger the cohesive interactions the more the heat required for the substance's transition into liquid and gas state.

These intermolecular forces include hydrogen bonding , ionic  bonding, dipole dipole, and Van Der Waals dispersion forces.

Because the atoms and molecules all have different properties
