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
