Qhov sib txawv tseem ceeb ntawm electropositive thiab electronegative radicals yog tias electropositive radicals yog radical compounds muaj peev xwm poob electrons thiab nqa ib tug zoo nqi whereas electronegative radicals yog radical compounds muaj peev xwm mus nce electrons thiab nqa ib tug tsis zoo nqi.
Ib radical, hauv chemistry, yog ib qho atom, molecule lossis ib qho ion uas muaj qhov tsis sib xws valence electron. Feem ntau, qhov tsis sib xws ntawm ib qho hluav taws xob no ua rau cov tshuaj lom neeg muaj zog heev vim tias cov hluav taws xob no nyiam ua ke nrog lwm cov hluav taws xob kom tau txais qib qis zog. Tsis tas li ntawd, lub atom, ion lossis molecule muaj lub plhaub qhib hluav taws xob uas muaj peev xwm tau txais cov khoom siv hluav taws xob kuj tau categorized li radical hauv chemistry. Vim muaj qhov ua tau zoo heev, cov radicals no feem ntau yuav dhau los ua qhov dimerization thiab cov tshuaj tiv thaiv polymerization.
Electropositive Radicals yog dab tsi?
Electropositive radicals yog atoms, ions, lossis molecules uas tuaj yeem poob ib qho hluav taws xob thiab nqa hluav taws xob zoo. Ib qho electropositive radical yog tsim los ntawm electropositive xwm ntawm ib hom tshuaj, uas txhais tau hais tias ib hom tshuaj muaj ib tug nyiam poob electrons nyob rau hauv thiaj li yuav tsim zoo radicals. Ntxiv mus, qee qhov piv txwv ntawm electropositive radicals suav nrog calcium cation (Ca+2), sodium cation (Na+), thiab lwm yam.

Electronegative Radicals yog dab tsi?
Electronegative radicals yog atoms, ions, lossis molecules uas tuaj yeem nce hluav taws xob thiab nqa hluav taws xob tsis zoo. Ib qho electronegative radical yog tsim los ntawm high electronegativity ntawm ib hom tshuaj, lub ntsiab lus, ib hom tshuaj muaj lub siab nyiam mus nce electrons thiab tsim tsis zoo nqi radicals.
Daim duab 02: Resonance hauv Radicals
Ntxiv mus, qee qhov piv txwv ntawm electronegative radicals suav nrog chlorine anion (Cl–), fluoride anion (F–), thiab lwm yam.
Qhov txawv ntawm Electropositive thiab Electronegative Radicals yog dab tsi?
Radicals yog hom tshuaj xws li atoms, ions, lossis molecules uas tsis muaj hluav taws xob tsis sib xws. Qhov tseem ceeb sib txawv ntawm electropositive thiab electronegative radicals yog tias electropositive radicals yog radical compounds muaj peev xwm rau electrons thiab nqa ib tug zoo nqi whereas electronegative radicals yog radical tebchaw muaj peev xwm mus nce electrons thiab nqa tus nqi tsis zoo. Yog li ntawd, electropositive radicals nqa ib tug zoo nqi thaum electronegative radicals nqa ib tug tsis zoo nqi. Qee qhov piv txwv ntawm electropositive radicals suav nrog calcium cation thiab sodium cation thaum cov piv txwv ntawm electronegative radicals suav nrog fluoride thiab chloride ions.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm electropositive thiab electronegative radicals.
Summary – Electropositive vs Electronegative radicals
Ib radical, hauv chemistry, yog ib qho atom, molecule lossis ib qho ion uas muaj qhov tsis sib xws valence electron. Qhov sib txawv tseem ceeb ntawm electropositive thiab electronegative radicals yog tias electropositive radicals yog radical compounds uas muaj peev xwm poob electrons thiab nqa ib tug zoo xwb whereas electronegative radicals yog radical tebchaw muaj peev xwm mus nce electrons thiab nqa ib tug tsis zoo nqi. Feem ntau, cov radicals yog cov tshuaj reactive heev uas ua rau lawv undergo dimerization thiab polymerization cov tshuaj tiv thaiv.
