Qhov qis dua qhov sib txawv ntawm electronegativity ntawm cov atoms sib koom, qhov qis dua qhov kev cog lus. O=O is non-polar; yog li ntawd, nws yog qhov tsawg tshaj plaws polar.
Koj paub li cas daim ntawv cog lus tsawg kawg nkaus?
Txhawm rau txiav txim siab qhov polarity ntawm daim ntawv cog lus, peb pom qhov sib txawv ntawm electronegativities ntawm cov atoms sib txuas. Cov txiaj ntsig electronegativity tuaj yeem tau txais los ntawm lub rooj sib tham. Qhov tsawg tshaj plaws polar daim ntawv cog lus yuav yog nruab nrab ntawm cov atoms muaj qhov sib txawv me tshaj plaws hauv electronegativity
Dab tsi yog qhov tsawg tshaj plaws polar molecule?
Txhua daim ntawv cog lus muaj polarity (txawm tsis muaj zog heev). Cov ntawv cog lus tau npaj symmetrically thiaj li tsis muaj tag nrho dipole hauv cov molecule. Lub diatomic oxygen molecule (O2) tsis muaj polarity nyob rau hauv covalent daim ntawv cog lus vim sib npaug electronegativity, li no tsis muaj polarity nyob rau hauv lub molecule.
Puas yog FF tsawg polar?
Txhawm rau txiav txim siab qhov polarity ntawm daim ntawv cog lus, koj saib ntawm electronegativity ntawm atoms hauv nqe lus nug. Txij li thaum fluorine (F), oxygen (O), nitrogen (N), thiab carbon (C) yog tag nrho nyob rau hauv tib kab ntawm lub sij hawm lub sij hawm, cov electronegativities yog yooj yim piv. … Qhov no yog rooj plaub rau F-F, yog li qhov no yog qhov tsawg tshaj plaws polar
Vim li cas co ntau polar dua tsis muaj?
Polarity. Lub polarity ntawm covalent daim ntawv cog lus nyob ntawm qhov sib txawv ntawm cov electronegativities ntawm cov atoms sib txuas. … Qhov no yog vim O yog electronegative ntau dua N uas yog electronegative ntau dua carbon. Daim ntawv cog lus C-O yog ntau dua liC-N daim ntawv cog lus uas yog ntau dua li C-C daim ntawv cog lus.
