Question

What is the significant interaction is weak enough to be easily disrupted; yet when many are present in large numbers, provides the stabilization necessary for larger structures such as DNA?

Select one:

a. Ionic bonding

b. Brownian motion

c. Hydrogen Bonding

d. Van der Waals

Movement of particles due to the random fluctuations of energy content of the environment is known as ____________.

Select one:

a. Brownian motion

b. van der Waals

c. entropy.

d. None of the above

Answer 1

1. d) van der waals

They are generally weak forces arising from the interaction of dipoles. They are non ionic and short range attractive forces. But in larger molecules they play an important role in maintaining the stability by attracting nearby molecules.

2. a) Brownian motion

It is the zig zag movement of molecules in a system caused by fluctuations in the surroundings.
