Qhov sib txawv tseem ceeb ntawm cov nyhuv inductive thiab cov nyhuv resonance yog cov nyhuv inductive tshwm sim vim yog polarization ntawm cov tshuaj bonds whereas resonance nyhuv tshwm sim vim muaj ib daim ntawv cog lus thiab ob daim ntawv cog lus ua ke.
Cov ntsiab lus inductive effect thiab resonance effect muaj feem xyuam rau atoms. Cov nyhuv inductive tshwm sim vim qhov cuam tshuam hluav taws xob nyob rau hauv atoms ntawm lub molecule. Txawm li cas los xij, cov nyhuv resonance tshwm sim thaum muaj ib daim ntawv cog lus thiab ob daim ntawv cog lus nyob rau hauv ib lub molecule nyob rau hauv ib tug alternating qauv.
Qhov cuam tshuam Inductive yog dab tsi?
Inductive effect tshwm sim vim kev xa hluav taws xob los ntawm cov saw hlau ntawm cov atoms. Thaum kawg, qhov kev sib kis no ua rau muaj hluav taws xob ruaj khov ntawm cov atom hauv cov molecule. Ntxiv mus, qhov tshwm sim no tshwm sim thaum lub electronegativity ntawm atoms nyob rau hauv tib molecule txawv ntawm ib leeg.
Daim duab 01: Kev Sib Cais Tus Nqi
Yeej, atoms nrog siab electronegativity qhov tseem ceeb nyiam nyiam daim ntawv cog lus electrons ntawm lawv dua li cov atoms uas tsis muaj electronegativity qhov tseem ceeb. Yog li ntawd, thaum muaj ob lub atoms nyob rau hauv ib tug covalent daim ntawv cog lus uas muaj ib tug siab sib txawv ntawm lawv cov electronegativity qhov tseem ceeb, qhov no induces lub qis electronegative atom kom tau ib feem zoo hluav taws xob nqi. Hauv qhov sib piv, lwm lub atom tau txais tus nqi tsis zoo, uas ua rau kev sib raug zoo polarization. Thiab, tag nrho cov txheej txheem no ua rau cov nyhuv inductive. Tsis tas li ntawd, muaj ob hom kev cuam tshuam; lawv yog cov nyhuv tshem tawm electron thiab electron tso tawm nyhuv.
Ntxiv mus, cov nyhuv inductive no muaj kev cuam tshuam ncaj qha rau kev ruaj ntseg ntawm cov molecules. Yog li, nws yog ib qho tseem ceeb tshwj xeeb hauv cov organic molecules. Piv txwv li, yog tias muaj ib feem zoo ntawm cov pa roj carbon atom hauv cov organic molecule, ces cov hluav taws xob tso tawm cov pab pawg xws li alkyl pab pawg tuaj yeem pub dawb lossis faib nws cov hluav taws xob nrog cov pa roj carbon atom, uas ua rau txo cov nqi zoo rau nws. Tom qab ntawd, kev ruaj ntseg ntawm cov organic molecule nce.
Resonance Effect yog dab tsi?
Resonance effect yog qhov cuam tshuam rau kev ruaj ntseg ntawm cov molecules nrog ob qho tib si thiab ob daim ntawv cog lus. Ib daim ntawv cog lus ob txhais tau hais tias muaj pi daim ntawv cog lus nrog rau daim ntawv cog lus sigma. Lub pi bond electron delocalization yog lub hauv paus ntawm cov nyhuv resonance. Ntawm no, tsis yog pi electrons xwb, tab sis kuj ib leeg electron khub yuav pab tau.
Daim duab 02: Resonance Stabilization ntawm Carbonate Ion
Cov molecules nrog ob daim ntawv cog lus nyob rau hauv ib qho kev hloov qauv qhia resonance thiab peb tuaj yeem siv cov qauv resonance thiaj li txiav txim siab cov tshuaj muaj pes tsawg leeg tsim los ntawm qee yam molecule. Nws yog vim hais tias cov molecule tau stabilized los ntawm resonance stabilization; Yog li, qhov tshwm sim tiag tiag ntawm ib lub molecule txawv ntawm cov molecule nrog alternating ob daim ntawv cog lus.
Qhov txawv ntawm Inductive Effect thiab Resonance Effect yog dab tsi?
Inductive effect yog ib qho txiaj ntsig uas tshwm sim vim kev xa hluav taws xob thoob plaws hauv cov saw hlau ntawm atoms. Cov nyhuv Resonance yog qhov cuam tshuam rau kev ruaj ntseg ntawm cov molecules nrog ob qho tib si thiab ob daim ntawv cog lus. Yog li ntawd, qhov sib txawv tseem ceeb ntawm cov nyhuv inductive thiab cov nyhuv resonance yog tias cov nyhuv inductive tshwm sim vim qhov polarization ntawm cov tshuaj bonds thaum cov nyhuv resonance tshwm sim vim muaj ib daim ntawv cog lus thiab ob daim ntawv cog lus ua ke.
Ntxiv mus, qhov txiaj ntsig ntawm electronegativity ntawm atoms hauv cov molecule cuam tshuam rau cov nyhuv inductive thiab tus lej ntawm ob daim ntawv cog lus thiab cov qauv ntawm lawv txoj haujlwm cuam tshuam rau cov nyhuv resonance. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm cov nyhuv inductive thiab cov nyhuv resonance.
Summary – Inductive Effect vs Resonance Effect
Inductive effect thiab resonance effect yog ob qho tseem ceeb ntawm cov tshuaj sib txuas. Qhov sib txawv tseem ceeb ntawm cov nyhuv inductive thiab cov nyhuv resonance yog tias cov nyhuv inductive tshwm sim vim qhov polarization ntawm cov tshuaj bonds thaum cov nyhuv resonance tshwm sim vim muaj ib daim ntawv cog lus thiab ob daim ntawv cog lus ua ke.
