Lub qhov pib ntawm ib qho amine yog nce los ntawm cov pab pawg neeg pub dawb thiab txo qis los ntawm cov pab pawg rho tawm electron. Aryl amines yog qhov yooj yim dua li alkyl-hloov amines vim tias qee qhov electron ceev muab los ntawm nitrogen atom raug faib thoob plaws lub nplhaib aromatic.
Vim li cas electron pub dawb pab pawg nce qib pib?
Vim Lewis lub hauv paus pub cov khoom siv hluav taws xob thiab Lewis acids lees txais lawv: cov khoom siv hluav taws xob thim rov qab yuav txo qis Lewis lub hauv paus ntawm cov chaw yooj yim thaum cov hluav taws xob pub cov neeg hloov pauv nce qhov chaw Lewis basicity los ntawm kev ua rau lawv ntau dua electron nplua nuj.
Puas electron pub pab pawg nce lossis txo acidity?
Ceeb toom: Cov pab pawg tshem tawm hluav taws xob nce acidity ntawm carboxylic acids. Ntawm qhov tod tes, electron pub pab pawg txo cov acidity ntawm carboxylic acidsvim lawv txo qhov polarity ntawm −OH daim ntawv cog lus ntawm −COOH pawg.
Yuav ua li cas electron rho tawm pawg cuam tshuam rau hauv paus?
Koj tuaj yeem nco qab tias electron rho tawm atoms (piv txwv li F lossis Cl) lossis pawg ua haujlwm (piv txwv li NO 2) nyiam ua kom acidity, by slurping tawm electron ceev los ntawm lub hauv paus conjugate. … Tus nqi qis dua=kev ruaj ntseg ntau dua=qhov pib qis dua.
Yuav ua li cas cov hluav taws xob tso tawm thiab hluav taws xob pub dawb pab pawg ua haujlwm cuam tshuam rau lub hauv paus ntawm amines?
Amines thiab ammonia
Qhov no yog vim cov electron pub dawb ntawm cov pab pawg alkyl uas nce cov electron ceev ntawm nitrogen Tertiary amines muaj ntau electron pub R pawg thiab nce cov electron ceev ntawm nitrogen kom ntau dua. … Li no qhov ntau R pab pawg amine muaj, qhov yooj yim dua nws yog.
