Qee Tshuaj Muaj Tseeb Txog Hexane
- tshuaj formula is C6H14.
- Molar mass yog 86.178 g/mol.
- Nws zoo li cov kua tsis muaj xim
- muaj roj tsw qab
- Melting point yuav nyob ntawm −96 txog −94 °C thiab qhov kub ntawm qhov kub ntawm 68.5 txog 69.1 °C.
Feem ntau, hexane muaj txiaj ntsig zoo hauv cov chaw sim ua cov kuab tshuaj tshem tawm kom tshem tawm cov roj thiab cov roj paug los ntawm dej lossis av. Tsis tas li ntawd, nyob rau hauv cov ntawv thov kev lag luam, hexane yog ib qho tseem ceeb hauv kev tsim cov kua nplaum rau cov khau, cov khoom tawv, thiab lwm yam. Tsis tas li ntawd, nws muaj txiaj ntsig zoo rau kev rho tawm cov roj ua noj los ntawm cov noob. Tsis tas li, hexane muaj txiaj ntsig zoo li cov kuab tshuaj tsis muaj polar nyob rau hauv cov ntawv thov chromatographic.
Qhov txawv ntawm Heptane thiab Hexane yog dab tsi?
Heptane yog cov organic compound uas muaj xya carbon atoms khi rau ib leeg ua ib qho alkane thaum hexane yog cov organic compound uas muaj rau carbon atoms sib koom ua ke ua ib qho alkane. Yog li, qhov sib txawv tseem ceeb ntawm heptane thiab hexane yog tias heptane muaj xya carbon atoms thaum hexane muaj rau carbon atoms.
Ntxiv mus, cov tshuaj formula ntawm heptane yog C7H16 thiab cov tshuaj formula ntawm hexane yog C 6 H14 Thaum xav txog kev tsim cov heptane thiab hexane, peb tuaj yeem tau txais heptane los ntawm Jeffrey Pine roj tab sis hexane tau los ntawm kev ua kom zoo roj av. Tsis tas li ntawd, ib qho sib txawv ntawm heptane thiab hexane yog tias heptane muaj cuaj isomers thaum hexane muaj tsib isomers.
Summary – Heptane vs Hexane
Ob leeg heptane thiab hexane yog cov organic tebchaw. Tsis tas li ntawd, lawv poob rau hauv qeb ntawm alkanes uas n ob lossis peb daim ntawv cog lus tam sim no. Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm heptane thiab hexane yog heptane yog alkane muaj xya carbon atoms whereas hexane yog alkane muaj rau carbon atoms.
