Electronegativity
- Definition
- Electronegativity is the ability of an atom to
attract a pair of electrons in a covalent bond.
- Electronegativity is the ability of an atom to
attract a pair of electrons in a covalent bond.
- Intermolecular force
- Van der Waal
- All molecules have VDW force>>>>> electrons
- Van der Waals' forces are attractive force
between induced dipoles in neighbouring
molecules
- Causes?
- By movement of electrons in the shell
- by the movement of electrons in the
shell and this movement unbalances
the distribution of charge with the
electron
- At any moment, there will be an
instantaneous dipole across the
molecule.
- The instantaneous dipole induces a
dipole in neighbouring molecules,
which in turn induce further dipoles
on the neighbouring molecules. The
small dipole attract on another
causing weak intermolecular force
- By movement of electrons in the shell
- All molecules have VDW force>>>>> electrons
- Permanent dipole
- Hydrogen Bonding
- Van der Waal
