1) Lawv xav tau electrons, txhais tau tias lawv tsis muaj hluav taws xob. 2) Lawv raug tawm tsam los ntawm nucleophiles. 3) Lawv raug nqi zoo, polar thiab / lossis polarizable. 4) Lawv ua zoo electrophiles nyob rau hauv lub xub ntiag ntawm Lewis acids.

Tsuas yog li ntawd, dab tsi yog Electrophile muaj zog?

Hauv organic chemistry, ib electrophile yog ib tug electron khub txais. Electrophiles yog zoo them los yog nruab nrab hom uas tsis muaj orbitals uas yog attracted rau ib tug electron nplua nuj chaw. Nws koom nrog cov tshuaj tiv thaiv los ntawm kev lees txais ib khub hluav taws xob txhawm rau txhawm rau txuas rau nucleophile.

Qhov thib ob, nucleophile thiab electrophile yog dab tsi? A Nucleophile Nws yog ib qho Reactant uas muab ib khub ntawm Electrons los tsim ib daim ntawv cog lus tshiabCovalent. Ib Hluav taws xob Yog Ib Tus Reactant uas lees txais ib khub ntawm Electrons los tsim Ib Daim Ntawv Cog Lus Tshiab. Nucleophilicity" Thiab "Electrophilicity" Xa mus rau qhov twg Ib hom tuaj yeem pub lossis txais ib khub Electrons.

Ua raws li qhov no, piv txwv Electrophile yog dab tsi?

Electrophiles yog atoms lossis molecules paub tias tsis muaj hluav taws xob thiab uas muaj ib feem (lossis tag nrho) cov nqi zoo thiab yuav nrhiav tau ib qho hluav taws xob los ua ib daim ntawv cog lus. Ib piv txwv ntawm ib electrophile yog Lewis Acid. Lwm yam piv txwv suav nrog Br+, Cl+, thiab CH3+.

Puas yog Electrophile zoo lossis tsis zoo?

Ib tug nucleophile yog ib tug nucleophile yog tias nws tsuas muaj ib tsis zoo nqi. Ib electrophile yog ib electrophile yog tias nws tsuas muaj ib zoo nqi. Rov qab tsis tau. Tab sis, ob qho tib si hom tuaj yeem ua rau nruab nrab thiab muaj zog heev kom lawv muaj zoo thiab cov tsis zoo xaus sib cais tab sis nyob rau hauv lub molecule.
