What causes molecules to be attracted or repelled from each other?

What causes molecules to be attracted or repelled from each other?

As two atoms/molecules approach each other they will feel the force of attraction caused by the electron density distortions, these are known as London dispersion forces (which we will abbreviate as LDF). The effects of these LDF’s depends upon their strength and on the atoms/molecules’ kinetic energies.

What makes molecules attracted to each other?

Atoms are the building blocks of chemistry. Each atom contains negatively and positively charged particles (electrons and protons). Atoms with a positive charge will be attracted to negatively charged atoms to form a molecule. This bonding between atoms is the key to how molecules interact with each other.

Do non-polar groups attract one another?

Nonpolar groups repel water. Nonpolar groups attract one another. hydrogen bonds between surface water molecules resist being stretched.

Do nonpolar molecules repel each other?

Non-polar molecules do not dissolve well in polar solutions like water; in fact, polar and non-polar molecules tend to repel each other in the same way that oil and water don’t mix and will separate from each other even if they are shaken vigorously in an attempt to mix them.

What happens when two atoms molecules collide?

In the first collision, the particles bounce off one another and no rearrangement of atoms has occurred. The second collision occurs with greater kinetic energy, and so the bond between the two red atoms breaks.

Is sugar a nonpolar compound?

Sugar is a polar substance. This is because it contains several polar OH groups which are comprised of a highly electronegative oxygen atom bonded…

How do nonpolar molecules attract each other?

When two non-polar molecules comes closer to each other. The negative part (electrons) of one molecule attract the positive part (nucleus) of another molecule. As a result, two dipoles are induced. Such dipoles are called induced dipoles and interaction is called induced dipole – induced dipole interactions.
