Yog tias tsis muaj ib leeg khub ces cov molecular geometry phim cov hluav taws xob thiab yog trigonal bipyramid. Lub hauv paus daim ntawv cog lus yog 180 °, 120 °, thiab 90 °. … POLARITY: POLAR - Ib khub electrons pov tseg qhov zoo kawg nkaus tshem tawm symmetry ntawm tsib trigonal bipyramidal cheeb tsam yog li ua rau tag nrho cov molecule polar.
Puas yog trigonal bipyramidal molecule puas yog NonPolar?
Trigonal Bipyramidal Piv txwv
Nonpolar. ob txoj haujlwm axial tsis zoo ib yam. peb txoj haujlwm equitorial yog tib yam.
Vim li cas trigonal pyramidal NonPolar?
Lub trigonal pyramid molecule yog symmetrical txog lub hauv paus B atom, yog li daim ntawv cog lus dipoles tshem tawm / muaj kev faib tawm ntawm tus nqi txog lub hauv paus atom. Pyramid Repulsion ntawm plaub thaj tsam ntawm tus nqi tsis zoo nyob ib puag ncig P - peb qhov kev sib txuas, ib qho tsis sib txuas PF3 yog polar.
Koj tuaj yeem qhia tau li cas yog lub molecule yog polar lossis nonpolar?
- Yog hais tias qhov kev npaj yog symmetrical thiab cov xub yog sib npaug ntev, cov molecule yog nonpolar.
- Yog cov xub sib txawv ntev, thiab yog tias lawv tsis sib npaug, lub molecule yog polar.
- Yog tias qhov kev npaj yog asymmetrical, lub molecule yog polar.
Koj txiav txim siab li cas yog tias ib yam dab tsi yog polar lossis nonpolar?
Cov ntsiab lus "polar" thiab "nonpolar" feem ntau yog hais txog covalent bonds. Txhawm rau txiav txim siab polarity ntawm covalent daim ntawv cog lus siv tus lej txhais tau tias,nrhiav qhov sib txawv ntawm electronegativity ntawm cov atoms; Yog tias qhov tshwm sim ntawm 0.4 thiab 1.7, ces, feem ntau, daim ntawv cog lus yog polar covalent.
