• # question_answer The compound containing co-ordinate bond is [AFMC 1999; Pb. CET 2002] A)                 ${{O}_{3}}$      B)                 $S{{O}_{3}}$ C)                 ${{H}_{2}}S{{O}_{4}}$  D)                 All of these

Co-ordinate bond is a special type of covalent bond which is formed by sharing of electrons between two atoms, where both the electrons of the shared pair are contributed by one atom. Since this type of sharing of electrons exits in ${{O}_{3}},$ $S{{O}_{3}}$ and ${{H}_{2}}S{{O}_{4}}$. Therefore all these contains coordinate bond.
