Why is carbon valency 4? The valency of carbon is 4. 1s2, 2s2, 2p2 are the outer electronic configurations of carbon. In this way, carbon has 4 asits valence electrons. Carbon uses these 4 valence electrons to form 4 covalent chains. Therefore, 4 is the valency of carbon. What is ...
RECENTLY, Long and Norrishhave shown that when the energy associated with the tetravalent state of carbon is systematically taken into account it is possible to bring order into the thermochemistry of carbon. They support the value of 190 kcal. for the latent heat of sublimation of graphite into...
