Why don't quadruple bonds occur very often?

Why don't quadruple bonds occur very often?

Quadruple bonds seem to make sense by the Lewis structure point of view, but when studied in an experimental level you'll see that it is difficult/impossible for quadruple bonds to occur because it would require the orbitals to point in certain directions/orientations, which they do not. This is the reason for these types of bonds not occurring very often.

[Manasvi Paudel 1A]

Quadruple bonds usually don't occur because of the octet rule as well. The octet rule would be fulfilled for an element in an ion if there were four bonds which means no other element could be bonded to it. It also would not contribute to a plausible shape for the ion.

There are cases of quadruple bonds in the transition metals. Transition metals have d-orbital which is required to form a quadruple bond.
