Now these two molecules differ by only one carbon atom and two little hydrogen atoms that ride along with it, and yet one of them, heptyl acetate, has the distinct odor of a pear, and hexyl acetate is unmistakably banana.
Keto molekula ndryshojne nga njera tjetra vec nga nje atom karbon dhe dy atome hidrogjen qe i vine pas karbonit, por njeri prej tyre, acetate heptyl, ka aromen e dardhes, ndersa acetate heksyl ate te bananes.
