A pab pawg ua haujlwm yog ib feem ntawm lub molecule uas yog ib tug recognizable/classified pab pawg ntawm bound atoms. Cov pab pawg ua haujlwm muab cov molecule nws cov khoom, tsis hais dab tsi molecule muaj nws; lawv yog cov chaw ntawm chemical reactivity. Cov pab pawg ua haujlwm nyob rau hauv ib lub molecule yuav tsum tau txheeb xyuas thaum lub npe.
Tsis tas li ntawd, koj txhais li cas los ntawm pab pawg ua haujlwm?
Functional Group . Cov pab pawg ua haujlwm txhais tias yog atom los yog pab pawg ntawm atoms koom nyob rau hauv ib tug tshwj xeeb yam, uas muab cov tshuaj muaj pes tsawg leeg ntawm cov organic compound thiab yog cov chaw rau tshuaj reactivity. Lawv muaj ib lub nplhaib benzene li cov pab pawg ua haujlwm.
Tom qab ntawd, lo lus nug yog, dab tsi yog pab pawg ua haujlwm thiab vim li cas lawv tseem ceeb? Cov pab pawg ua haujlwm yog tseem ceeb hauv chemistry vim lawv yog ib feem ntawm cov molecule uas muaj peev xwm ntawm cov yam ntxwv tshwm sim. Lawv Yog li ntawd, txiav txim siab cov khoom thiab chemistry ntawm ntau cov organic tebchaw. Ib qho organic compound yog ib qho kev sib xyaw uas muaj cov pa roj carbon thiab lwm cov khoom.
Hais txog qhov no, dab tsi yog cov yam ntxwv ntawm cov pab pawg ua haujlwm?
A pab pawg ua haujlwm yog a pab pawg ntawm atoms nrog rau lub cev, tshuaj, thiab reactivity zog. Cov pab pawg ua haujlwm nyob rau hauv cov organic chemistry yog ib qho tseem ceeb rau ntau lub ntsiab lus yav tom ntej, nrog rau lawv cov kev kwv yees yam ntxwv , nomenclature, reactivity, synthesis, spectroscopy, thiab lwm yam.
Dab tsi yog 7 pawg ua haujlwm?
Muaj 7 pawg ua haujlwm tseem ceeb hauv chemistry ntawm lub neej: Hydroxyl , Carbonyl , Carboxyl , Amino , Thiol, Phosphate , thiab aldehyde pawg. 1) Hydroxyl pawg : muaj hydrogen atom covalently bonded rau ib tug oxygen atom.
Pom zoo:
Dab tsi ua haujlwm pab pawg yog hydrophilic?

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 yog pab pawg ua haujlwm Chem?
Ib pab pawg ua haujlwm yog ib feem ntawm cov molecule uas yog ib pawg neeg paub / cais ntawm cov atoms khi. Nyob rau hauv cov organic chemistry nws yog heev uas pom cov molecules muaj feem ntau ntawm cov pa roj carbon qaum nrog cov pab pawg ua haujlwm txuas rau cov saw hlau
Dab tsi yog pawg ua haujlwm hauv molecules?
Cov pab pawg ua haujlwm yog cov pab pawg tshwj xeeb ntawm atoms hauv cov molecules uas muaj lawv tus kheej cov yam ntxwv, tsis hais txog lwm cov atoms tam sim no hauv amolecule. Cov piv txwv feem ntau yog cawv, amines, carboxylicacids, ketones, thiab ethers
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
