Alkyl halides muaj me ntsis kom tsis muaj solubility hauv dej txawm tias muaj cov pa roj carbon-halogen daim ntawv cog lus. Lub attraction ntawm alkyl halide molecules muaj zog tshaj qhov attraction ntawm alkyl halide thiab dej. Alkyl halides muaj me ntsis tsis muaj solubility hauv dej, tab sis yuav tsum paub txog qhov ntom ntom.
Vim li cas alkyl halides insoluble hauv dej?
Teb: (a) Alkyl halides yog insoluble nyob rau hauv dej vim lawv tsis muaj peev xwm tsim hydrogen bonds Piav: H-bonds yog tsim thaum hydrogen bonded nrog heev electronegative atom zoo li F, O los yog N. Nyob rau hauv alkyl halides hydrogen yog bonded tsuas yog cov pa roj carbon uas tsis tshua muaj electronegative.
Vim li cas alkyl halides tsis soluble dej txawm tias polar?
Alkyl halides yog polar nkaus xwb vim yog qhov hloov pauv halogenQhov alkyl yog hydrophobic nyob rau hauv cov xwm txheej uas tawm tsam cov dej molecules. Qhov loj dua qhov hydrophobic no yog qhov ntau insoluble uas alkyl halide ua. Yog li ntawd, me me alkyl halides yog haum rau soluble hauv dej.
Puas yog alkyl halides polar?
Alkyl halides yog polar hauv xwm vim qhov sib txawv ntawm electronegativity ntawm carbon thiab halogen atoms. Halogens yog electronegative ntau dua li cov pa roj carbon monoxide, vim tias cov hluav taws xob sib txuas tau hloov mus rau halogen atom ua rau daim ntawv cog lus polar. Yog li, alkyl halides txawm tias polar yog immiscible nrog dej.
Puas halides yaj hauv dej?
Halides yog anion daim ntawv ntawm halogen atoms, uas nyob rau hauv pawg 7 ntawm lub sij hawm. Feem ntau halides pom nyob rau hauv cov dej ntuj muaj xws li fluoride, chloride, thiab bromide. Halides muaj nyob rau hauv cov dej ntuj, xws li dej ntws, pas dej, thiab cov kwj deg, vim lawv siab solubility hauv dej
Pom zoo:
Puas yog nag lossis daus soluble hauv dej?
Precipitates yog insoluble ionic khoom khoom ntawm cov tshuaj tiv thaiv, tsim thaum qee cov cations thiab anions ua ke hauv cov tshuaj aqueous. Qhov kev txiav txim siab ntawm kev tsim cov nag lossis daus tuaj yeem sib txawv . Puas nag los yaj hauv dej?
Puas yog hentriacontane soluble hauv dej?
Hentriacontane yog ib qho hydrophobic molecule, insoluble hauv dej, thiab siab nruab nrab . Hentriacontane siv rau dab tsi? CHEBI:5659 - hentriacontane Ib yam khoom uas kills lossis slows kev loj hlob ntawm Mycobacterium tuberculosis thiab yog siv los kho tuberculosis .
Puas yog alkyl halides dej soluble?
Alkyl halides muaj me ntsis rau tsis muaj solubility nyob rau hauv dej txawm tias muaj polar carbon-halogen daim ntawv cog lus. Lub attraction ntawm alkyl halide molecules muaj zog tshaj qhov attraction ntawm alkyl halide thiab dej. Alkyl halides muaj me ntsis tsis muaj solubility hauv dej, tab sis yuav tsum paub txog qhov ntom ntom .
Puas yog triacylglycerols soluble hauv dej?
Triglycerides yog tag nrho insoluble hauv dej. Txawm li cas los xij, vim yog pawg ionic organic phosphate, phospholipids qhia cov khoom vim tias pawg ionic nyiam dej . Vim li cas triacylglycerols insoluble hauv dej? Triglycerides yog insoluble hauv dej vim lawv tsis muaj nqi piv txwv li lawv muaj covalent bonds… Triglycerides muaj polar (them) taub hau thiab tsis muaj polar fatty acid tails yog li tus nqi ntawm cov molecule yog unevenly faib.
Puas yog dej sodium soluble lossis rog soluble?
Vitamins yog cais raws li cov rog soluble (vitamin A, D, E thiab K) los yog dej soluble (vitamin B thiab C). Qhov sib txawv ntawm ob pawg no tseem ceeb heev. Nws txiav txim siab seb txhua cov vitamin ua li cas hauv lub cev. Cov vitamins muaj roj soluble yog soluble hauv lipids (fas) .
