A pab pawg ua haujlwm yog ib feem ntawm lub molecule uas yog ib tug recognizable/classified pab pawg ntawm bound atoms. Hauv cov organic chemistry Nws yog qhov pom zoo kom pom cov molecules feem ntau ntawm cov pob txha carbon nrog pab pawg ua haujlwm txuas rau cov saw hlau.
Tsuas yog li ntawd, 6 hom kev ua haujlwm yog dab tsi?
Cov pab pawg ua haujlwm muaj xws li: hydroxyl , methyl, carbonyl , carboxyl , amino phosphate, thiab sulfhydryl.
Ib tug kuj yuav nug, dab tsi yog pab pawg ua haujlwm piv txwv? Hauv organic chemistry, a pab pawg ua haujlwm yog ib txheej ntawm atoms nyob rau hauv molecules uas muaj nuj nqi ua ke los teb rau hauv txoj kev kwv yees. Piv txwv ntawm pab pawg ua haujlwm suav nrog hydroxyl pab pawg ua ketone pab pawg , muaj pab pawg , thiab ether pab pawg.
Tsis tas li ntawd, pawg ua haujlwm alkyl yog dab tsi?
Definition: Ib alkyl yog a pab pawg ua haujlwm ntawm cov organic tshuaj uas tsuas muaj cov pa roj carbon thiab hydrogen atoms, uas yog teem nyob rau hauv ib tug saw. Lawv muaj cov qauv dav dav C H2 ib n+1. Piv txwv xws li methyl CH3 (los ntawm methane) thiab butyl C2H5 (ua los ntawm butane).
Puas yog chloride yog pab pawg ua haujlwm?
Rau kev lom lom pab pawg ua haujlwm yog hydrogen, hydroxyl, carboxyl, amino, phosphate, thiab methyl. Cov haloalkanes muaj cov qauv dav dav R-X qhov twg R- sawv cev rau qee cov alkyl lossis aryl pab pawg thiab -X sawv cev rau ib qho ntawm cov tswv cuab ntawm tsev neeg halogen: fluorine, tshuaj chlorine , bromine thiab / lossis iodine.
Pom zoo:
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
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
Dab tsi ua haujlwm pab pawg tseem ceeb tshaj plaws rau lub zog ntawm tes?
Nrog plaub lub electronegative oxygen atoms, phosphate pawg yog cov reactive heev, thiab kev hloov ntawm ib pab pawg phosphate los ntawm ib tug molecule mus rau lwm tus muab lub zog rau cov tshuaj tiv thaiv. ATP, lub luag haujlwm tseem ceeb hauv lub hlwb, yog tsim los ntawm peb pawg phosphate sib koom ua ke
Dab tsi yog pab pawg ntawm cov hlwb uas ua haujlwm zoo ib yam?
Cov ntaub so ntswg yog pab pawg ntawm cov hlwb zoo sib xws uas muaj kev ua haujlwm zoo sib xws. Lub cev yog ib qho qauv uas muaj tsawg kawg yog ob lossis ntau hom ntaub so ntswg thiab ua haujlwm tshwj xeeb rau lub cev. Ntau lub cev ua haujlwm ua ke kom ua tiav ib lub hom phiaj yog hu ua lub cev
Dab tsi ua haujlwm pab pawg koj yuav kwv yees yog ib feem ntawm abscisic acid ABA)?
Dab tsi ua haujlwm pab pawg koj yuav twv seb yog ib feem ntawm abscisic acid (ABA)? Cov tshuaj muaj cov carboxyl functional pawg (-COOH) hu ua carboxylic acids lossis organic acids
