Study Notes

Magnetic Moment

Magnetic moment (m s) is directionally oriented with a spin of +1/2 or -1/2.
Two electrons in the same orbital must have opposite spins.

Hybridization

Hybridization (sp) occurs in Group II elements and unsaturated acetylenic compounds of carbon.
The improved directional characteristics of the hybrid orbitals should be noted.

Oxygen Hybridization

Oxygen achieves a hybridized valence state.
In sp3 hybridization, the water molecule would have two lone pairs of electrons in hybridized orbitals.
The oxygens can be rotated to align their p orbitals parallel to the carbon p orbitals, This leads to two volumes of electron density separated by a nodal plane at the bond axis.

Dipole

The positive end of the dipole is produced by protons in the nuclei and attracts electrons in the same or a neighboring species.
