Heptane yog cov organic compound uas muaj xya carbon atoms khi rau ib leeg, tsim ib qho alkane. Nws tseem muaj 16 hydrogen atoms. Tag nrho cov atoms no tsim C-H bonds nrog carbon atoms. Yog li ntawd, muaj C-C daim ntawv cog lus thiab C-H daim ntawv cog lus nyob rau hauv no compound.
Cov tshuaj formula ntawm heptane yog C7H16. Cov molar loj ntawm cov khoom no yog 100.2 g / mol. Nws zoo nkaus li cov kua tsis muaj xim ntawm chav tsev kub thiab siab. Ntxiv mus, heptane muaj roj tsw qab. Nws yog tshwj xeeb tshaj yog pab tau raws li ib tug nonpolar hnyav. Heptane tuaj yeem yaj ntau cov organic sib txuas thiab tuaj yeem ua raws li cov kuab tshuaj extracting.
Heptane tuaj yeem muaj nyob hauv ntau hom isomeric. Cov kuab tshuaj no muaj cov ntawv thov loj hauv kev paub qhov txawv ntawm aqueous bromine los ntawm aqueous iodine los ntawm kev rho tawm ntawm aqueous bromine rau hauv heptane. Feem ntau, ob qho tib si bromine thiab iodine tshwm hauv xim xim av. Tab sis thaum yaj hauv cov kuab tshuaj heptane, iodine tau txais cov xim ntshav thaum bromine tseem nyob hauv xim xim av.
Ntawm kev lag luam nplai, heptane muaj nyob rau hauv kev sib xyaw ntawm isomers uas siv rau hauv cov xim thiab txheej. Nws muaj txiaj ntsig zoo hauv cov khoom siv roj hmab xws li "Bestine" ntau lawm, "Powerfuel" (qhov cub sab nraum zoov), thiab lwm yam.
N-Heptane yog dab tsi?
N-Heptane yog cov qauv tsis muaj ceg ntawm heptane molecule. Cov duab hauv qab no qhia cov qauv tshuaj ntawm N-Heptane.
Muaj ntau cov isomers thiab enantiomers ntawm heptane molecule vim tias muaj xya carbon atoms nyob rau hauv cov molecule no uas tuaj yeem npaj rau ntau hom kev ua cov qauv thiab cov chaw chiral. Piv txwv li, isoheptane, neoheptane, 3-methylhexane, thiab lwm yam.
Kev sib raug zoo ntawm Heptane thiab N-Heptane yog dab tsi?
Feem ntau, peb siv lo lus heptane xa mus rau txhua qhov sib txawv isomers ntawm 7-carbon alkane molecule. Cov qauv tshuaj ntawm heptane molecule tuaj yeem sib txawv ntawm ntau txoj hauv kev nyob ntawm kev sib txuas ntawm atomic thiab ceg. Yog tias muaj cov saw ncaj ntawm 7 carbon atoms yam tsis muaj kev hloov pauv lossis cov ceg txuas nrog cov saw hlau (tsuas yog, cov saw hlau ncaj nraim ntawm 7 carbon atoms, txhua cov pa roj carbon sib txuas rau hydrogen atoms los tsim cov saturated molecule), peb hu nws n - heptane los yog ib txwm heptane.
Qhov txawv ntawm Heptane thiab N-Heptane yog dab tsi?
Cov tshuaj formula ntawm heptane yog C7H16. Nws yog tshwj xeeb tshaj yog pab tau raws li ib tug nonpolar hnyav. Heptane tuaj yeem yaj ntau cov organic sib txuas thiab tuaj yeem ua raws li cov kuab tshuaj extracting. Qhov sib txawv tseem ceeb ntawm heptane thiab n-heptane yog tias heptane yog ib qho organic compound uas muaj xya carbon atoms teem nyob rau hauv ob ceg los yog tsis-branched lug, whereas n-heptane yog cov tsis-branched qauv ntawm heptane molecule. Ntxiv mus, cov khoom ntawm heptane tuaj yeem sib txawv nyob ntawm cov qauv tshuaj, qhov N-heptane yog cov tsis muaj polar, cov kua tsis muaj xim muaj ntxhiab tsw ntxhiab.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm heptane thiab n-heptane.
Summary – Heptane vs N-Heptane
Cov tshuaj formula ntawm heptane yog C7H16. Nws yog tshwj xeeb tshaj yog pab tau raws li ib tug nonpolar hnyav. Heptane tuaj yeem yaj ntau cov organic sib txuas, thiab nws tuaj yeem ua raws li cov kuab tshuaj extracting. Qhov sib txawv tseem ceeb ntawm heptane thiab n-heptane yog tias heptane yog ib qho organic compound uas muaj xya carbon atoms teem nyob rau hauv ob ceg los yog tsis-branched lug, whereas n-heptane yog cov tsis-branched qauv ntawm heptane molecule.
