Default Does carbon form quadruple bond?

Thanks for clearing this out for me, it does make perfect sense. I
have another question though. Suppose you have an sp3 carbon-carbon
bond. According to VSEPR theory the e- clouds repel each other, thus
forming angles of 109.5 degress. Trying to disrupt these angles
requires much energy, and is therefore not stable. But what is the
case, for example, of cyclopropane? (three carbons forming a triangle,
with 2 hydrogens attached to each). This is a stable molecule, even
though the angle strain is great (in this case both carbons are sp3
hybridized). This molecule allows the strain in its angles because it
lacks the one extra hydrogen at the end of each carbon (thus forming
two methyl groups). My question is the following: why are we not able
to disrupt the strain in the angles of an sp3 hybrized-carbon to form
a quadruple bond with another carbon? the energy required to do so,
theoretically, wouldnt be much greater than that found in
cyclopropane. I'll appreciate any guidance...

I meant to say that heavier elements have a "less structured", "more
flexible", electron clouds. Such is the case of Sulfur (e.g. SF6),
which can form an expanded valence shell becuase of its electron cloud
density. Also, this is the reason why Silicon, being a 4th group
element, and having similar properties as Carbon, does not behave
exactly as carbon--the "elektron" cloud is larger and therefore a bit
more stable (more electrons to satify the oppostie charge)

Yes, i do have Linux OS. Though, i found a good software for WIN OS
called ACD/ChemSketch.
