Q.
Which type of bond is present in $ {{H}_{2}}S $ molecule?
BHUBHU 2006
Solution:
Electronic configuration of $ _{16}{{S}^{32}}=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{4}} $ .
In the last orbit it has only six electrons. So, it requires 2 electrons to complete its octet. Therefore, it share 2 electrons with two hydrogen atom and forms 2 covalent bond with it.
