Amides tsis tshua muaj zog dua li cov esters vim qhov tseeb tias nitrogen txaus siab pub nws cov khoom siv hluav taws xob ntau dua li cov pa oxygenVim li ntawd, ib nrab tus cwj pwm zoo ntawm carbonyl carbon yog me me nyob rau hauv amides tshaj nyob rau hauv esters, ua rau lub cev no tsawg electrophilic.
Vim li cas amides tsis muaj zog?
Amides yog qhov ruaj khov tshaj plaws, thiab qhov ua tsis zoo tshaj plaws, vim nitrogen yog cov khoom siv hluav taws xob zoo rau pawg carbonylAnhydrides thiab esters tsis ruaj khov, vim tias oxygen ntau dua electronegative tshaj nitrogen thiab yog ib tug tsis zoo pub dawb ntawm electrons.
Vim li cas amines muaj zog dua amides?
Lub ib khub ntawm electrons ntawm amine muaj ntau dua los txais cov proton thiab ua lub hauv paus Qhov no yog vim hais tias nyob rau hauv amides, carbonyl (C=O) pab pawg neeg yog heev electronegative, yog li muaj lub zog ntau dua los kos cov electrons ntawm nws, ua rau ib leeg ntawm amide nitrogen tsis muaj txaus los txais ib tug proton.
Vim li cas amides thiaj li muaj zog?
Amides yog tsim nyog rov ua haujlwm, feem ntau yog los ntawm kev tawm tsam ntawm carbonyl rhuav tshem cov carbonyl ob daim ntawv cog lus thiab tsim cov tetrahedral nruab nrab. … Raws li lawv qhov kev ruaj ntseg resonance, amides tsis tshua muaj zog nyob rau hauv lub cev muaj zog tshaj li esters.
Vim li cas amides qhov tsawg tshaj plaws reactive carboxylic acid derivative?
Resonance electron pub dawb los ntawm Y txo qis tus cwj pwm electrophilic ntawm carbonyl carbon. Cov nyhuv resonance muaj zog tshaj plaws tshwm sim hauv amides, uas nthuav tawm ntau cov pa roj carbon-nitrogen ob daim ntawv cog lus thiab yog qhov tsawg tshaj plaws ntawm cov derivatives.
