Valence plhaub electron khub repulsion txoj kev xav, los yog VSEPR txoj kev xav (/ˈv?sp?r, v?ˈs?p?r/ VESP-?r, v?-SEP-?r), yog ib qho qauv siv hauv chemistry los kwv yees qhov geometry ntawm ib tug neeg molecules los ntawm cov xov tooj ntawm electron khub nyob ib ncig ntawm lawv central atoms.
Hauv qhov no, Vsepr txhais li cas?
Valence Plhaub Electron Pair Repulsion theory
Ib yam li ntawd, Vsepr txoj kev xav nrog piv txwv yog dab tsi? VSEPR Cov ntawv sau muab cov qauv dav dav rau kev faib cov tshuaj lom neeg raws li tus naj npawb ntawm cov khoom hluav taws xob nyob ib ncig ntawm lub hauv paus atom. Nco ntsoov, txawm li cas los xij, tsis yog txhua hom tsiaj muaj tib lub molecular geometry. Rau piv txwv , carbon dioxide thiab sulfur dioxide yog ob hom, tab sis ib qho yog linear thiab lwm yam yog khoov.
Tsuas yog li ntawd, cov duab Vsepr yog dab tsi?
Basic Cov duab Yog li raws li tag nrho cov xov tooj ntawm electron khub, muaj ob peb yam yooj yim cov duab thiab khi cov ces kaum uas peb xav tau nco. 2 electron khub - linear. 3 electron khub - trigonal planar. 4 electron khub - tetrahedral. 5 electron khub - trigonal bipyramidal.
Puas yog h2o polar lossis nonpolar?
Ib tug dej molecule, abbreviated li H2O , yog ib qho piv txwv ntawm a polar covalent bond. Cov electrons tsis sib npaug, nrog rau cov pa atom siv sij hawm ntau nrog cov hluav taws xob ntau dua li cov hydrogen atoms. Txij li thaum electrons siv sij hawm ntau nrog cov pa atom, nws nqa ib feem tsis zoo nqi.

Lub ntsiab lus ntawm dav hlau geometry yog dab tsi?
Hauv kev ua lej, lub dav hlau yog lub tiaj tus, ob sab ntawm qhov chaw uas txuas mus tsis kawg. Lub dav hlau yog ob-dimensional analogue ntawm ib qho point (zero dimensions), ib kab (ib dimension) thiab peb-dimensional qhov chaw
Dab tsi yog qhov molecular geometry ntawm if4 -?
IF4 (iodine tetrafluoride) muaj octahedral electron geometry, tab sis cov molecular geometry hais tias cov atoms coj ib tug square planar duab. Qhov no yog vim iodine nqa ob leeg ib leeg, ib qho saum toj thiab hauv qab lub dav hlau ntawm x-axis
Dab tsi yog cov duab zoo hauv geometry?
Cov duab khoom yog cov duab peb sab uas muaj qhov ntev, dav thiab qhov siab. Saib qee qhov piv txwv ntawm cov duab peb sab hauv qab no. Lub prism yog ib lub polyhedron nrog raws nraim ob lub ntsej muag uas yog congruent thiab parallel. Cov ntsej muag no hu ua lub hauv paus. Lwm lub ntsej muag hu ua lateral faces
