# Can carbon have quadruple bonds? [duplicate]

Carbon has 4 valence electrons, so it means that it can have a total of four (covalent) bonds, correct?

If that's the case, why can't carbon share four bonds, such as with another carbon atom (to form $\ce{C2}$, for example)?

• The question about fullerenes would probably be best asked as a separate question, with a link back to this one if you really want. – chipbuster Aug 13 '15 at 1:54
• Have you heard of Valence Bond Theory (orbital hybridization), VSEPR theory, or MO theory? – chipbuster Aug 13 '15 at 1:58
• I have removed the extra fluff outta your question. We really don't need to know about how you learned about the uncertainty principle. The questions should be free-of-noise and stick to the point. We have Chemistry Chat if you want casual conversation with users of the site. – M.A.R. Aug 13 '15 at 5:29

• Side note: $\ce{C2}$ molecule is more interesting than one might think. – M.A.R. Aug 13 '15 at 5:28
