(C) Dimerisation ntawm benzoic acid: Hydrogen daim ntawv koom nrog hauv dimerisation ntawm benzoic acid vim H atom ntawm ib cov kua qaub molecule cuam tshuam nrog O atom ntawm cov nyob sib ze acid molecule los ntawm hydrogen bonding. Li no tsis muaj dative daim ntawv cog lus nrog rau qhov no thiab.
Cov piv txwv ntawm daim ntawv cog lus yog dab tsi?
Ib qho piv txwv ntawm dative covalent daim ntawv cog lus yog muab los ntawm kev sib cuam tshuam ntawm a molecule ntawm ammonia, Lewis puag nrog ib leeg ib khub ntawm electrons ntawm nitrogen atom, thiab boron trifluoride, Lewis acid los ntawm kev tsim txiaj ntawm boron atom muaj qhov tsis tiav octet ntawm electrons.
Qhov twg tsis muaj kev sib koom tes?
[{mathbf{B}}{{mathbf{F}}_4}^ - ]: Fluorine shares ib leeg ib khub electron nrog Boron lub khoob 2p orbital tsim kom muaj kev sib koom tes. … Yog li tsis muaj kev sib koom tes sib cog lus. \[{mathbf{N}}{{mathbf{H}}_4}^ + ]: kev sib koom ua ke yog tsim los ntawm ib leeg khub ntawm nitrogen kom khoob 1s orbital ntawm hydrogen.
Qhov twg ntawm cov molecule hauv qab no tsis muaj kev sib koom tes?
Lub molecule uas tsis muaj daim ntawv cog lus yog $C{O_3}^{2 - }$.
Ntawm twg ntawm daim ntawv cog lus hauv qab no tsis muaj?
Cov nyiaj hauv ammonia molecule yog tsim los ntawm kev sib npaug ntawm cov electrons los ntawm nitrogen thiab hydrogen atoms. Yog li, ammonia molecule muaj covalent bonds. Yog li, qhov kev sib koom ua ke tsis muaj nyob hauv ammonia molecule.
