Carbon looks divalent but actually it is tetra valent. Explain.

Answer:
before reading make me brainlist!!!
explaination:
six electrons of the carbon atom are distributed as: 1S2 2S2 2P2 these atomic orbitals will combine to form various molecular orbitals, these will be used for chemical bonding. Always tetravalent as there are four electrons in the n=2 level, for tetrahedral molecules as methane and alkane series it is four SP3 orbitals ready to join a 1S hydrogen orbital and then four SP3-S sigma bond, forming ethane a planar molecule (each carbon tetravalent) the molecular orbital for each carbon is three SP2 and leaving each a free 2P atomic orbital as there are three: 2Px, 2Py and 2Pz. The ethane molecule is with four SP2-S sigma carbon-hydtogen, one sigma C-C SP2-SP2 bond and the free atomic 2P will form a pi bond (double bond as it is above and below the ethane plane.tion:
