Question 19

Three molecules (A, B, C) with the following chemical formulas examined for their rates of diffusion through agar. The molecules are:

A    C₆H₁₂O₆
B    C₄N₂0₁H₁₀
C    C₆N₂O₂H₁₀

Which of the three molecules will migrate the furthest in a set amount of time?

B

They will all migrate the same distance in the same amount of time

None of the molecules will migrate without the addition of outside energy

A

C

Solution

Agar gel, when solidified, has pores small enough for small molecules like antibiotics and solvents to diffuse through it. However, molecules like C₆H₁₂O₆, C₄N₂O₁H₁₀, and C₆N₂0₂H₁₀ are much too large to pass through the pores of the gel. These molecules will not be able to diffuse through the gel.

Thus, the correct answer is: none of the molecules will migrate without the addition of outside energy.
