Pentane muaj nyob ua peb isomers: n-pentane (feem ntau hu ua "pentane"), isopentane ( 2-methylbutane ) thiab neopentane ( dimethylpropane ).

Ib yam li ntawd, isomer ntawm pentane yog dab tsi?

N- pentane , 2-methylbutane, thiab 2-ethylpropane yog peb cov qauv isomers ntawm pentane . 2-methylbutane thiab 2-ethylpropane yog branched thiab yog li ruaj khov dua.

Kuj Paub, uas isomer ntawm pentane yog compact tshaj? Cov feem ntau compact isomer ntawm pentane yog 2, 2-dimethylpropane.

Tsis tas li ntawd, 3 isomers ntawm pentane yog dab tsi?

Muaj 3 lub npe isomers ntawm pentane:

  • n-pentane - ncaj saw ntawm 5 carbon atoms.
  • methybutane (isopentane) - ib pawg methyl txuas rau 2ndcarbon ntawm cov saw tseem ceeb ntawm plaub.
  • dimethylpropane (neopentane) - 2 pawg methyl uas txuas rau cov pa roj carbon monoxide ntawm 3 carbon central saw (tetrahedral inshape).

Ib qho piv txwv ntawm isomer yog dab tsi?

Butane thiab isobutane muaj tib cov pa roj carbon (C) atoms thiab hydrogen (H) atoms, yog li lawv cov qauv molecular yog tib yam. Txawm li cas los xij, txhua tus muaj cov qauv qauv sib txawv, uas qhia tau hais tias cov atoms tau teeb tsa li cas. Yog li peb tuaj yeem hais tias butane andisobutane yog cov qauv isomers.
