Study Notes
Molecule Polarity
- Polarity of molecules is defined as a measure of the unequal sharing of electrons between atoms in a covalent bond.
- The unequal sharing of electrons occurs due to the difference in electronegativity between atoms.
Electronegativity
- Electronegativity is the ability of an atom to attract electrons in a covalent bond.
- It is a measure of the atom's ability to pull electrons towards itself.
Octet Rule
- The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer energy level of eight electrons.
- This rule helps in predicting the number of bonds an atom can form and the type of bonds it can form.
Distribution of Electrons
- Molecules with equal or symmetrical distribution of electrons are non-polar molecules.
- Molecules with unequal or asymmetrical distribution of electrons are polar molecules.
- The unequal distribution of electrons occurs due to the difference in electronegativity between atoms.
