Qhov sib txawv tseem ceeb ntawm isopentane thiab neopentane yog tias cov isopentane muaj plaub-tus tswvcuab carbon saw nrog ib pawg methyl txuas rau cov saw no ntawm cov pa roj carbon thib ob ntawm cov saw hlau thaum lub neopentane muaj ib lub chaw carbon txuas nrog plaub methyl. pab pawg.
Isopentane thiab neopentane yog cov qauv isomers ntawm ib leeg. Yog li ntawd, ob qho tib si cov tebchaw muaj tib yam tshuaj formula; C5H12 Txawm li cas los xij, vim qhov sib txawv ntawm isopentane thiab neopentane hauv lawv cov qauv tshuaj, lawv muaj cov tshuaj lom neeg thiab lub cev sib txawv. Lwm qhov sib txawv tseem ceeb ntawm isopentane thiab neopentane yog tias isopentane muaj nyob hauv cov kua tsis muaj xim thaum neopentane yog cov roj tsis muaj xim ntawm tus qauv kub thiab siab.
Isopentane yog dab tsi?
Isopentane yog cov organic compound uas muaj cov tshuaj formula C 5H12 thiab muaj nyob hauv cov kua tsis muaj xim ntawm qhov ntsuas kub thiab siab. Lub npe IUPAC ntawm cov tshuaj no yog 2-Methylbutane. Ntxiv mus, nws yog ib tug ceg alkane uas muaj plaub-tus tswv cuab cov saw hlau nrog ib pawg methyl txuas rau cov saw hlau no, ntawm cov pa roj carbon thib ob ntawm cov saw hlau. Yog li ntawd, nws yog ib qho tsis tshua muaj volatile thiab flammable kua.
Daim duab 01: Cov Qauv Tshuaj ntawm Isopentane
Qhov tseem ceeb tshaj, nws yog cov kua dej tsawg tshaj plaws ntawm qhov ntsuas kub thiab siab. Yog li ntawd, lub boiling point tsuas yog ob peb degrees saum toj no lub chav tsev kub. Yog li ntawd nws yooj yim boils tsim nws vapor. Cov molar mass ntawm no compound yog 72.15 g / mol. Lub melting point thiab boiling point yog nyob rau hauv thaj tsam ntawm −161 mus rau -159 ° C thiab 27.8 mus 28.2 ° C feem.
Neopentane yog dab tsi?
Neopentane yog cov organic compound uas muaj cov tshuaj formula C5H12 thiab muaj nyob hauv cov roj tsis muaj xim ntawm qhov ntsuas kub thiab siab. Nws yog tus qauv isomer ntawm pentane. Nws yog ob ceg alkane uas muaj ib lub chaw carbon txuas nrog plaub pawg methyl. Ob ceg tshwm sim ntawm nruab nrab cov pa roj carbon atom ntawm peb-tus tswv cuab cov saw hlau.
Daim duab 02: Cov Qauv Tshuaj ntawm Neopentane
IUPAC lub npe ntawm cov tshuaj no yog li 2, 2-Dimethylpropane. Yog li ntawd, lub molecule no muaj ib tug tetrahedral geometry. Tsis tas li ntawd, nws tshwm sim raws li cov pa roj cua ntawm chav tsev kub thiab siab. Yog li ntawd, nws muaj peev xwm condense mus rau hauv ib tug heev volatile kua nyob rau hauv ib tug txias hnub, yog hais tias peb muab tso rau hauv ib tug dej khov da dej los yog yog hais tias peb compress nws thov kom haum siab. Lub melting point thiab boiling point yog -16.5 ° C thiab 9.5 ° C raws.
Qhov txawv ntawm Isopentane thiab Neopentane yog dab tsi?
Isopentane yog cov organic compound uas muaj cov tshuaj formula C5H12 thiab muaj nyob hauv cov kua xim tsis muaj xim ntawm qhov ntsuas kub thiab siab thaum neopentane yog cov organic compound uas muaj cov tshuaj formula C5H12 thiab tshwm sim raws li cov roj tsis muaj xim ntawm qhov ntsuas kub thiab siab. Ntawm no, peb yuav tsum nco ntsoov tias txawm tias lawv muaj tib yam tshuaj formula; C5H12,lawv muaj cov qauv tshuaj sib txawv. Qhov ntawd yog vim lawv yog cov qauv isomers ntawm ib leeg. Lub isopentane muaj plaub-tus tswvcuab cov saw hlau nrog ib pawg methyl txuas rau cov saw no ntawm cov pa roj carbon thib ob ntawm cov saw hlau thaum lub neopentane muaj ib lub chaw carbon txuas nrog plaub pawg methyl. Li no, qhov no yog qhov sib txawv tseem ceeb ntawm isopentane thiab neopentane.
Tsis tas li, vim qhov sib txawv ntawm lawv cov qauv tshuaj, peb tuaj yeem txheeb xyuas qee qhov sib txawv ntawm isopentane thiab neopentane hauv lawv cov khoom siv tshuaj. Ntxiv mus, lawv ob leeg muaj nyob rau hauv txawv lub cev lub xeev ib yam nkaus thiab. Isopentane muaj nyob hauv cov kua tsis muaj xim thaum neopentane yog cov roj tsis muaj xim ntawm tus qauv kub thiab siab. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm isopentane thiab neopentane.
Summary – Isopentane vs Neopentane
Isopentane thiab neopentane yog cov qauv isomers ntawm ib leeg. Yog li ntawd lawv muaj tib cov tshuaj formula tab sis txawv cov qauv tshuaj. Qhov sib txawv tseem ceeb ntawm isopentane thiab neopentane yog tias isopentane muaj plaub-tus tswvcuab carbon saw nrog ib pawg methyl txuas rau cov saw no ntawm cov pa roj carbon thib ob ntawm cov saw hos neopentane muaj ib lub chaw carbon txuas nrog plaub pawg methyl.
