Carbon thiab hydrogen muaj ze rau tib lub electronegativity, lub zog ntawm attraction ntawm ib tug electron rau ib tug atom. Nws ua raws li hais tias ib qho hluav taws xob sib koom ntawm lawv yog sib npaug rau ob qho tib si. Qhov no tiv thaiv a dipole lub sijhawm los ntawm kev tsim, wherece propane ( C3H8 ) yog tsis muaj polar.

Yog li, yog propane polar lossis nonpolar?

Propane yog Tsis muaj polar . Txij li thaum carbon thiab hydrogen muaj cov electronegativities zoo sib xws (2.5 rau C thiab 2.2 rau H) C-H bonds hauv tshuaj propane yuav luag covalent (EN txawv = 0.3). Ib tug yuav hu lawv tsis muaj polar ”. Tau kawg, C-C daim ntawv cog lus yog covalent kiag li (thiab kuj, tau kawg, tsis muaj polar ).

Kuj Paub, yog c3h8 yog dipole dipole? Nws muaj ib tug Lewis qauv ntawm: Exhibits dipole thiab London dispersion rog tab sis tsis muaj hydrogen bonding vim nws tsis muaj H covalently bonded rau O. Propane, C3H8 , muaj 3(4) + 8(1) = 20 valence electrons. Propane tsuas muaj cov ntawv cog lus uas tsis muaj polar, yog li nws tsis yog polar.

Tsis tas li ntawd, daim ntawv cog lus dab tsi yog c3h8?

LUB TSWV YIM C3H8 YOG ALKANE NAME PROPANE nyob rau hauv tag nrho cov ALKANE Cov CARBON yog khi los ntawm ib leeg COVALENT BOND THIAB REST BONDS Ntawm CARBON tau ua tiav HYDROGEN

Kuv yuav ua li cas thiaj paub tias daim ntawv cog lus yog polar?

Rau txiav txim polarity ntawm covalent daim ntawv cog lus siv tus lej txhais tau tias, nrhiav qhov sib txawv ntawm electronegativity ntawm cov atoms; yog qhov tshwm sim yog nruab nrab ntawm 0.4 thiab 1.7, ces, feem ntau, lub daim ntawv cog lus yog polar covalent.
