WebThree atomic orbitals on each carbon – the 2 s, 2 px and 2 py orbitals – combine to form three sp 2 hybrids, leaving the 2 pz orbital unhybridized. The three sp 2 hybrids are arranged with trigonal planar geometry, pointing to the three corners of an equilateral triangle, with angles of 120°between them. WebThe most common exceptions to the octet rule are the so-called hypervalent compounds. These are species in which there are more atoms attached to a central atom than can be accommodated by an octet of electrons. ... Hypervalent compounds are very common and in general are no less stable than compounds that conform to the octet rule.
