Muaj ob txoj hauv kev uas isomers tuaj yeem sib txawv. Thaum lawv sib txawv ntawm txoj kev sib txuas ntawm cov atoms, lawv hu ua kev cai lij choj isomers kev cai lij choj isomers Hauv chemistry, cov qauv isomer (los yog kev cai lij choj isomer hauv IUPAC nomenclature) ntawm ib qho kev sib txuas yog lwm qhov sib xyaw uas nws cov molecule muaj tib tus lej. ntawm cov atoms ntawm txhua lub caij, tab sis nrog logically sib txawv bonds ntawm lawv . Lo lus metamer yav tas los siv rau tib lub tswv yim. https://en.wikipedia.org › wiki › Structural_isomer
Structural isomer - Wikipedia
. Butane thiab isobutane, piv txwv li, yog txoj cai isomers. … Cov pa roj carbon atoms hauv C=C ob daim ntawv cog lus hauv 2-butene, piv txwv li, yog stereocenters.
Puas butene muaj ob daim ntawv cog lus?
Nws yog qhov yooj yim tshaj plaws ntawm cov alkenes, muaj ob lub pa roj carbon atom txuas nrog ob daim ntawv cog lus. Qhov no tso tawm txhua cov pa roj carbon monoxide rau kev sib txuas rau ob lub hydrogen atoms. … 1-Butene muaj cov saw hlau ntawm plaub carbons, muaj ib ob daim ntawv cog lus ntawm carbons 1 thiab 2.
Puas yog butane ib daim ntawv cog lus ob lossis ob?
Propane, butane, thiab isobutane yog tag nrho cov hydrocarbons uas tsuas yog ib leeg covalent bonds ntawm cov pa roj carbon atoms. Cov hydrocarbons uas tsis muaj ob daim ntawv cog lus, triple daim ntawv cog lus, los yog lub nplhaib tsim ua cov chav hu ua alkanes. Rau qhov yooj yim alkanes yog methane, ethane, propane, butane, pentane, hexane, thiab windowspane.
Puas butane muaj daim ntawv cog lus triple?
Yog li, qhov sib xyaw no muaj 4carbons thiab yog ib tug butane carbon saw, thiab ntxig rau infix -yn- muab lub npe: butyne, tab sis txoj hauj lwm ntawm qhov pib ntawm lub triple daim ntawv cog lusyuav tsum tau teev tseg. … Cov niam txiv lub npe ntawm qhov sib xyaw no yog octane thiab triple daim ntawv cog lus pib ntawm C3. Yog li, niam txiv lub npe ntawm lub compound yog: 3-octyne.
Puas yog propane ob daim ntawv cog lus?
Propane, C₃H₈, yog ib qho alkane ib txwm muaj peb cov pa roj carbon atom. Ethene, C₂H₄, yog qhov tsawg tshaj plaws alkene, nrogib C=C ob daim ntawv cog lus. … Cov no yog raws li qhov tseeb tias carbon ib txwm siv plaub daim ntawv cog lus (thiab hydrogen tsuas yog siv ib qho khi), yog li tsim cov nplhaib uas pom hauv qhov piv txwv saum toj no.
