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

  • question_answer The bond that exists between \[N{{H}_{3}}\] and \[B{{F}_{3}}\]is called                 [AFMC 1982; MP PMT 1985; MNR 1994; KCET 2000; MP PET 2001; UPSEAT 2001]

    A)                 Electrovalent    

    B)                 Covalent

    C)                 Coordinate        

    D)                 Hydrogen

    Correct Answer: C

    Solution :

                    \[N{{H}_{3}}\] has lone pair of electron while \[B{{F}_{3}}\] is electron deficient compound so they form a co-ordinate bond. \[N{{F}_{3}}\to B{{F}_{3}}\]
