MCQ
Which type of bond is present in ${H_2}S$ molecule
  • A
    Ionic bond
  • ✓
    Covalent bond
  • C
    Co-ordinate
  • D
    All of three
✓

Answer

Correct option: B.
Covalent bond
(b)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 $6$ electron. So it require $2$ electron to complete its octet, therefore it share $2$ electron with two hydrogen atom and forms $2$ covalent bond with it.
