Solvolysis , ib qho tshuaj lom neeg cov tshuaj tiv thaiv uas cov kuab tshuaj, xws li dej los yog cawv, yog ib qho ntawm cov reagents thiab muaj ntau tshaj qhov xav tau rau cov tshuaj tiv thaiv. Cov kuab tshuaj ua los yog tsim cov electron-nplua nuj atoms los yog pawg ntawm atoms (nucleophiles) uas txav ib lub atom los yog pab pawg nyob rau hauv lub substrate molecule.
Ib yam li ntawd, koj tuaj yeem nug, yog Solvolysis sn1 lossis sn2?
Solvolysis . Solvolysis yog ib hom kev hloov pauv nucleophilic (SN1) / (SN2) los yog tshem tawm, qhov twg cov nucleophile yog cov kuab tshuaj molecule. Yam ntxwv ntawm SN1 cov tshuaj tiv thaiv, solvolysis ntawm ib tug chiral reactant them rau racemate.
Dab tsi txiav txim Solvolysis tus nqi? Polar protic cov kuab tshuaj ua kom ceev cov tus nqi ntawm unimolecular hloov cov tshuaj tiv thaiv vim hais tias lub sij hawm loj dipole ntawm cov kuab tshuaj pab stabilize lub xeev hloov. Qee zaum hauv SN1 cov tshuaj tiv thaiv cov kuab tshuaj ua raws li cov nucleophile. Qhov no hu ua a solvolysis tshuaj tiv thaiv (saib piv txwv hauv qab).
Kuj nug, Solvolysis puas tuaj yeem yog e1?
Cov E1 Mechanism. Peb tau pom tias 3o alkyl halides yog nquag solvolysis cov tshuaj tiv thaiv hauv polar-protic cov kuab tshuaj. Txawm li cas los xij, raws li daim duab 1 qhia, kev hloov pauv nucleophilic feem ntau yog nrog los ntawm kev tsim cov alkene, piv txwv li tshem tawm.
Ammonolysis muab piv txwv li cas?
Ammonolysis - thaum ammonia ua raws li cov nucleophile thiab reacts nrog cov organic compound. Rau piv txwv , chlorobenzene reacting nrog ammonia rau muab ib qho amine raws li cov khoom.

Koj txhais qhov hnyav txhais li cas?
Cov ntsiab lus. Weighted Mean: Ib qho txhais tau tias qee qhov txiaj ntsig pab ntau dua li lwm tus. Thaum qhov hnyav ntxiv rau 1: tsuas yog muab txhua qhov hnyav los ntawm tus nqi sib xws thiab suav tag nrho. Txwv tsis pub, muab txhua qhov hnyav w los ntawm nws qhov sib piv tus nqi x, suav tias tag nrho, thiab faib los ntawm qhov sib npaug ntawm qhov hnyav: Qhov Ntsuas Ntsuas = ΣwxΣw
Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Txhais tau li cas los txhais ib daim duab peb sab?
Kev txhais lus. Kev txhais lus yog ib qho kev hloov pauv uas tshwm sim thaum ib daim duab tau txav los ntawm ib qho chaw mus rau lwm qhov chaw yam tsis tau hloov nws qhov loj, duab lossis kev taw qhia. Txhawm rau txhais cov ntsiab lus P (x, y), ib chav nyob sab xis thiab b units, siv P'(x + a, y + b)
