Octant rule is the one which is used to correlate the sign of the cotton effect.
NH3 is not an exception to the octet rule. Nitrogen (N) in NH3 has a total of 8 valence electrons (5 from nitrogen and 3 from hydrogen), fulfilling the octet rule. Nitrogen has 3 bonded pairs and 1 lone pair of electrons, following the octet rule.
Hund's rule is violated in this configuration. According to Hund's rule, electrons will fill empty orbitals before pairing up in the same orbital. In this case, the electrons should have filled the 2py and 2pz orbitals first before pairing up in the 2px orbital.
CF4 and XeF4 do not violate the octet rule. In CF4, carbon forms four covalent bonds with fluorine, fulfilling the octet rule. In XeF4, xenon forms four covalent bonds with fluorine and has two lone pairs, also satisfying the octet rule.
The key difference between the Zaitsev and Hofmann rule in organic chemistry is that the Zaitsev rule states that the major product of a reaction is the more substituted alkene, while the Hofmann rule states that the major product is the less substituted alkene.
BCl3 and BEH2 obey the octet rule because Boron and Beryllium are exceptions to the octet rule and can have stable electron configurations with less than 8 electrons. Cl3CF, NO, and SbF5 do not obey the octet rule because they have incomplete or expanded valence shells.
Isaac Newton invented the reflecting octant in 1699.
The octant was invented by British mathematician and astronomer John Hadley in 1730. Hadley's octant was a navigation instrument used to measure the altitude of celestial bodies, helping sailors to determine their position at sea.
There are 45 degrees in an octant because an octant is 1 eighth of a circle, and a circle is 360 degrees, and 45 degrees is one eighth of 360.

The octant rule is a principle used in various fields, including mathematics and computer graphics, to determine the spatial orientation of points in three-dimensional space. It divides the space into eight distinct regions (or octants) based on the signs of the coordinates (x, y, z). Each octant corresponds to a unique combination of positive and negative values for these coordinates, helping to simplify calculations and visualizations in 3D environments. This rule is particularly useful in algorithms for 3D rendering and spatial analysis.
One eighth of a circle.
Octant
There is 45 degrees in an octant. This is equivalent to one eighth of a circle. Since a circle has 360 degrees you would divide this number by 8.
