Chapter U2.14, Problem 4E

Interpretation Introduction

Interpretation :

Correct option must be chosen for the ability to smell a newly created molecule with different three dimensional shapes from other molecules.

Concept Introduction :

Smell of a molecule is obtained only when it is bound to nasal receptor and produces a nerve impulse which reaches brain.

Answer to Problem 4E

Correct answer:

Option C is correct answer.

Explanation of Solution

Reason for correct option:

As the molecule is newly created which has different three dimensional shape thus, there is no receptor for the new molecule. Thus, the molecule will not bind with our nasal receptor.

Conclusion

Reasons for incorrect options:

Option A is incorrect as all synthetic molecules are not smell free.

Option B is incorrect as the new molecule might not be esters.

Option D is incorrect as the molecule might not break off to fit into receptor sites in our nose.
