Cov lub hom phiaj ntawm nkhaus xub yog qhia kev txav ntawm electrons ntawm ib qhov chaw mus rau lwm qhov. Cov hluav taws xob txav ntawm tus Tsov tus tw mus rau lub taub hau. Feem ntau ntawm xub koj yuav pom muaj ob-barb ntawm lub taub hau, sawv cev rau kev txav ntawm ib khub ntawm electrons.
Kuj tseem yuav paub yog, dab tsi ua rau cov xub nkhaus hauv cov tshuaj tiv thaiv sawv cev?
Hauv kev siv xub thawb, " nkhaus xub "los yog" curly xub "yog superimposed tshaj cov qauv qauv ntawm reactants nyob rau hauv ib tug tshuaj kev sib npaug qhia cov tshuaj tiv thaiv tshuab. Cov xub Piav qhia qhov txav ntawm electrons raws li kev sib txuas ntawm cov atoms tawg thiab tsim.
Ib tug kuj yuav nug, Electrophile thiab Nucleophile yog dab tsi? Electrophile thiab Nucleophile . Electrophile thiab nucleophile yog hom tshuaj uas pub dawb lossis txais cov khoom siv hluav taws xob los tsim ib daim ntawv cog lus tshiab. A nucleophile yog ib hom tshuaj uas muaj feem xyuam rau cov lus teb, muab ib khub electron los tsim ib daim ntawv cog lus tshuaj. Zuag qhia tag nrho, electron-nplua nuj yog a nucleophile.
Yog li ntawd, cov xub txhais li cas hauv organic chemistry?
Xub hauv chemistry tau muab broadly classified as 'reaction xub ' thiab 'electron xub '. Thaum yav tas los siv los piav txog lub xeev lossis kev vam meej ntawm a tshuaj cov tshuaj tiv thaiv, tom kawg yog siv los sawv cev ntawm kev txav ntawm electrons.
Electrophilic reagent yog dab tsi?
Electrophilic reagents yog hom tshuaj uas, nyob rau hauv cov chav kawm ntawm cov tshuaj tiv thaiv, tau txais electrons, los yog ib feem ntawm electrons, los ntawm lwm yam molecules los yog ions.
