Why carbon cannot form tetravalent bond with itself |
| Answer» The reason a\xa0carbon\xa0atom\xa0cannot bond\xa0with four electrons with another\xa0carbon\xa0is due to the\xa0carbon\xa0electron orbitals. Since it has a s and 3 p orbitals, it must create one sigma and at most 2 pi\xa0bonds\xa0with another\xa0carbon. Hence, you\'ll have to\xa0bond\xa0them with another atom.\xa0Carbon\xa0can\xa0not form 4 bonds\xa0with another\xa0carbon\xa0because of its orbitals which are some time hybridized. ... In case of ethyne it shows sp hybirdization and two p unhybird orbitals\xa0forms\xa0two pi\xa0bonds\xa0with other atom and two hybrid orbitals\xa0forms\xa0sigma\xa0bonds\xa0one with\xa0carbon\xa0and other with hydrogen. | |
