Question

give a reason why one atom of carbon shares four electrons one with each chlorine during the formation of covalent molecule carbon tetrachloride

Answer 1

Carbon shares 4 atom as carbon has 4valence electron it has a capacity of sharing 1 electron each with 1chlorine electron, this how carbon 4atom shares 1,1,1,1 electron with 4chlorine

Answer 2

Answer:

C-atomic no. = 6 = 2, 4, has 4 valence electrons, it cannot lose 4 electrons also it cannot gain 4 electrons for energy considerations. Hence C atom shares valence electrons. Each atom of Cl has 7 electrons in outer most orbit and can gain 1 electron. Hence to attain octet i.e. 8 electrons in valence shell it needs 4 Cl-atoms to form covalent molecule of CCl4.
