TXC 3CH 3 tuaj yeem yog a Lewis puag , thiab BBr3 tuaj yeem yog Bronsted-Lowry kua qaub . TXC 3CH 3 tuaj yeem yog a Lewis puag , BBr3 tuaj yeem yog Bronsted-Lowry kua qaub , thiab CH3Cl tuaj yeem yog a Lewis puag.
Hais txog qhov no, puas yog ch3ch3 acid lossis base?
TXC 3CH 3 , tsis yog kua qaub . Nws yog hydrocarbon, ua los ntawm carbon thiab hydrogen atoms nkaus xwb. Qhov no hydrocarbon belongs rau homologous series hu ua alkanes, thiab yog hu ua ethane. Nws tsis muaj cov pab pawg ua haujlwm hauv nws cov qauv molecular rau nws kom muaj kev nyiam ntawm cov dej molecules uas yog polar hauv qhov xwm txheej.
Ib tug kuj nug, puas yog txhua lub hauv paus Lewis tseem yog Bronsted Lowry hauv paus? Yog lawm, tag nrho cov Brosted - Lowry hauv paus yog Lewis puag tab sis tag nrho cov Lewis bases tsis yog Brosted - Lowry puag . Txhua tus Brosted - Lowry hauv paus yuav tsum muaj ib tug khub los txais ib tug hydrogen, thiab tag nrho cov Lewis bases muaj ib khub. Thaum, Lewis Bases tuaj yeem ua raws li nucleophiles rau txhua tus atoms: B, Al , C, thiab lwm yam; thiab tsis yog rau H.
Raws li, qhov twg tsis yog Lewis acid?
Lub compound uas yog tsis yog Lewis acid yog. NF3 yog tsis yog lewis acid nws yog a lewis puag. Lewis acids tuaj yeem txais ib leeg khub thaum lewis bases pub ib leeg txij li NF3 muaj ib leeg ib khub thiab tuaj yeem pub dawb, nws yog ib qho lewis puag.
Lub hauv paus muaj zog yog dab tsi?
Cov hauv paus muaj zog muaj peev xwm ua kom tiav hauv dej
- LiOH - lithium hydroxide.
- NaOH - sodium hydroxide.
- KOH - poov tshuaj hydroxide.
- RbOH - rubidium hydroxide.
- CsOH - cesium hydroxide.
- *Ca(OH)2 - calcium hydroxide.
- *Sr(OH)2 - strontium hydroxide.
- * Ba(OH)2 - barium hydroxide.

Puas yog ch4 a Lewis acid lossis base?
Ib tug xov tooj ntawm pawg 14 elemental hydrides: CH4, SiH4, GeH4 & SnH4, yog inert rau Lewis acid thiab Lewis puag reagents. (Cov hom tuaj yeem raug oxidised thiab lawv raug cuam tshuam los ntawm radicals thiab diradicals.) Yog li methane yog Lewis puag tab sis, zoo li helium, nws yog ib qho tsis tshua muaj zog proton abstractor
Puas yog beryllium yog hlau lossis nonmetal lossis metalloid?
Beryllium yog hlau. Nws yog nyob rau hauv alkaline ntiaj teb hlau pawg nyob rau hauv lub periodic lub rooj thiab muaj tshuaj thiab lub cev muaj zog zoo ib yam li cov magnesium thiab txhuas, tab sis muaj ib tug ntau dua melting point tshaj ob qho tib si
Hom kev sib cog lus twg yog tsim thaum Lewis acid reacts nrog Lewis puag?
Sib koom covalent bond
Puas yog h3o+ Lewis acid lossis base?
Yog, twv yuav raug hu! Lewis acids yog cov khoom siv hluav taws xob. Thaum lub H3O + poob ib tug proton (H +), nws yuav tsum tau txais ib tug electron khub ntawm lub tawg daim ntawv cog lus rau proton, yog li muab peb H2O thiab ua raws li ib tug Lewis acid. Los ntawm lub caij nyoog, tag nrho cov Bronsted-Lowry acids (proton pub) yog Lewis acids, tab sis tsis yog lwm txoj kev
Puas yog acid rau dej lossis dej rau acid?
Thaum tshav kub kub tau tso tawm ntau heev uas cov tshuaj yuav ua rau kub hnyiab heev, txaws concentrated acid tawm ntawm lub thawv! Yog tias koj ntxiv cov kua qaub rau hauv dej, cov tshuaj uas cov ntaub ntawv yog diluted heev thiab qhov me me ntawm cov cua sov tso tawm tsis txaus rau vaporize thiab spatter nws. Yog li Ib txwm Ntxiv Acid rau dej, thiab tsis txhob thim rov qab
