Hydrophilic functional pawg suav nrog hydroxyl pab pawg (ua rau muaj cawv txawm tias tseem pom muaj suab thaj, thiab lwm yam), carbonyl pab pawg (ua rau aldehydes thiab ketones), carboxyl pab pawg (ua rau carboxylic acids), amino pab pawg (piv txwv li, raws li pom nyob rau hauv cov amino acids), sulfhydryl pab pawg (ua rau thiols, i.e., raws li pom
Tib neeg kuj nug, dab tsi ua haujlwm pab pawg yog hydrophobic?
Ib qho piv txwv ntawm ib pawg hydrophobic yog cov tsis-polar methane molecule. Ntawm cov hydrophilic functional pawg yog cov pawg carboxyl pom hauv amino acids , ib co amino acid sab chains, thiab fatty acid taub hau uas tsim triglycerides thiab phospholipids.
Tsis tas li ntawd, cov pab pawg twg ua haujlwm tau soluble hauv dej? Ob pawg ua haujlwm uas muaj cov pa oxygen, pawg hydroxyl thiab carbonyl, pab txhawb dej solubility.
- Hydroxyl pawg muaj ib qho hydrogen ua ke nrog ib lub atom oxygen (symbolized li -OH).
- Cov pa roj carbon monoxide muaj ib lub atom ob npaug rau carbon atom (symbolized li C = O).
Tib neeg kuj nug, yog pawg hydroxyl hydrophilic lossis hydrophobic?
Cawv. Hydroxyl pawg (- OH ), pom nyob rau hauv cawv, yog polar thiab yog li ntawd hydrophilic (dej ling) tab sis lawv cov pa roj carbon saw feem tsis yog-polar uas ua rau lawv hydrophobic . Cov molecule nce zuj zus tag nrho cov tsis muaj polar thiab yog li ntawd tsawg soluble nyob rau hauv lub polar dej raws li cov carbon saw ntev.
Cov pab pawg twg ua haujlwm tau raug ionization?
Carboxylic acid yog kev sib koom ua ke ntawm a carbonyl pawg thiab a pawg hydroxyl txuas nrog tib cov pa roj carbon monoxide, ua rau muaj cov yam ntxwv tshiab. Cov pawg carboxyl tuaj yeem ionize, uas txhais tau tias nws tuaj yeem ua raws li ib qho kua qaub thiab tso cov hydrogen atom los ntawm lub pawg hydroxyl raws li ib tug dawb proton (H+).

Cov pab pawg twg ntawm cov ntsiab lus tsuas muaj tsis yog hlau?
Kev piav qhia: Pawg VIIA yog tib pawg hauv lub sijhawm uas txhua lub ntsiab lus yog nonmetals. Cov pab pawg no muaj F, Cl, Br, I thiab At.Lwm lub npe ntawm pab pawg no yog halogen uas txhais tau tias cov khoom siv ntsev
Dab tsi ua haujlwm pab pawg yog hydrophilic?
Cov pab pawg ua haujlwm hydrophilic muaj xws li pawg hydroxyl (ua rau muaj cawv txawm tias tseem pom muaj suab thaj, thiab lwm yam), pawg carbonyl (ua rau aldehydes thiab ketones), pawg carboxyl (ua rau carboxylic acids), pawg amino (piv txwv li, raws li pom hauv cov amino acids. ), sulfhydryl pawg (ua rau thiols, piv txwv li, raws li pom
Cov pab pawg twg ntawm cov ntawv teev sijhawm twg yog cov tshuaj chlorine?
Chlorine belongs rau pab pawg neeg ntawm halogens - ntsev tsim - ua ke nrog fluorine (F), bromine (Br), iodine (I) thiab astatine (At). Lawv tag nrho nyob rau hauv kab thib ob los ntawm sab xis ntawm lub rooj sib tham hauv Pawg 17. Lawv cov teeb tsa hluav taws xob zoo sib xws, muaj xya lub tshuab hluav taws xob hauv lawv lub plhaub sab nraud
Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
Cov pab pawg twg hauv qab no ntawm kev tshawb fawb txog kev ua haujlwm ib puag ncig zoo sib xws?
Teb: D) Environmental activist, ib puag ncig tus kws lij choj Nyob rau hauv cov kev xaiv, ib puag ncig activists thiab ib puag ncig tus kws lij choj yog ib puag ncig science cov hauj lwm uas zoo sib xws. Lub hom phiaj tseem ceeb ntawm cov kws tshaj lij no yog kev tiv thaiv ib puag ncig
