Answer 39

The distribution of electrical charge among the atoms connected by a chemical bond

Question 40

What is a dipole?

Answer 40

A separation of electrical charge within a molecule or a bond, resulting in one end being partially positive (δ+) and the other end being partially negative (δ-)

Question 41

What is a partial charge?

Answer 41

A fractional, non-integer charge on an atom or a region of a molecule

Question 42

What is the polarity scale?

Answer 42

a measure of the degree of charge separation within a covalent bond, ranging from nonpolar to highly polar

Question 43

What is the definition of the intermolecular known as London Dispersion forces?

Answer 43

These are weak, temporary attractions arising from instantaneous fluctuations in electron distribution within molecules. They are present in all molecules and increase in strength with larger, more polarizable molecules

Question 44

What is the definition of the intermolecular known as Dipole-Dipole?

Answer 44

These forces occur between polar molecules due to the attraction between the partially positive and negative ends of the molecules. A molecule with a permanent dipole moment will be attracted to other polar molecules with a similar dipole moment.

Question 45

What is the definition of the intermolecular known as Hydrogen Bonds?

Answer 45

This is a special type of dipole-dipole interaction that occurs when a hydrogen atom bonded to a highly electronegative atom (like nitrogen, oxygen, or fluorine) is attracted to another highly electronegative atom. Hydrogen bonds are generally stronger than other dipole-dipole interactions.
