JEE Main & Advanced Chemistry Chemical Bonding and Molecular Structure Question Bank Co-ordinate or Dative bonding

  • question_answer A simple example of a coordinate covalent bond is exhibited by                                [NCERT 1984]

    A)                 \[{{C}_{2}}{{H}_{2}}\]    

    B)                 \[{{H}_{2}}S{{O}_{4}}\]

    C)                 \[{{H}_{2}}O\]  

    D)                 \[HCl\]

    Correct Answer: B

    Solution :

               \[{{H}_{2}}S{{O}_{4}}\] has co-ordinate covalent bond.                                 \[H-O-\underset{O}{\overset{O}{\mathop{\underset{\downarrow }{\overset{\uparrow }{\mathop{S}}}\,}}}\,-O-H\]
