Interpretation:
The relation between chemistry and smell needs to be explained.
Concept introduction:
Smell is a complex process in which binding of some molecules takes place inside our nose. Smell of a molecule depends on the type of

Explanation of Solution
Molecules have different shapes which are complimentary with the nasal receptor. Those molecules which are structurally fitting with the receptor will give the sensation of smell.
Different chemicals are there which have characteristic smell. For example,ethyl acetate has fruity smell because of the esters have sweet smell. As molecules have different functional groups so those have different bonding interaction with nasal receptors which attibutes for the diversity in smell of different compounds.
Smelling is a complex biochemical reaction taking place between receptor and molecules. This diversity comes from the functional groups present in a chemical.

Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right.

Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure. You can add any substituents using the pencil tool in the usual way. Click and drag to start drawing a structure. Х аarrow_forwardPredict the major products of this organic reaction.
