Thib ob, CH3 pawg hauv acetaldehyde txo qis tus nqi zoo ntawm cabonyl carbon los ntawm +Kuv cuam tshuam rau qee qhov extect uas tsis yog li ntawd nyob rau hauv rooj plaub ntawm formaldehyde, Txij li, Nu nres yog qhov zoo nrog ntau tus nqi zoo. thiab tsawg dua kev cuam tshuam ntawm carbonyl carbon, yog li peb xaus lus tias formaldehyde yog ntau reactive dua …
Vim li cas acetaldehyde ntau reactive?
Vim qhov loj thiab loj ntawm pawg phenyl, steric hindrance tshwm sim los ntawm benzaldehyde ntau dua acetaldehyde. … Yog vim li cas, acetaldehyde reactive dua benzaldehyde thiab acetone yog reactive dua benzophenone.
Vim li cas formaldehyde reactive dua acetaldehyde thiab acetone?
Vim qhov no cov electron ntom ntom ntawm carbonyl carbon nce ua rau nws tsawg dua electrophilic, rau kev tawm tsam ntawm nucleophile thaum nyob rau hauv rooj plaub ntawm formaldehyde tsis muaj methyl pawg yog li nws muaj ntau dua. reactive tshaj acetone. …
Vim li cas formaldehyde reactive tshaj plaws?
Thaum cov nucleophile tawm tsam cov aldehyde lossis ketone carbon, cov nucleophile uas tuaj yeem thawb cov electrons hauv pi daim ntawv cog lus rau oxygen, carbon yuav ua rau qee qhov zoo thiab cov pa oxygen ib nrab tsis zoo. … Li no, los ntawm cov kab zauv saum toj no peb tuaj yeem hais tias Formaldehyde ntau dua reactive rau nucleophilic ntxiv cov tshuaj tiv thaiv.
Vim li cas aldehydes ntau reactive dua?
Aldehydes feem ntau yog ntau duareactive than ketones vim yog cov hauv qab no. … Cov carbonyl carbon nyob rau hauv aldehydes feem ntau muaj ib nrab nqi zoo tshaj nyob rau hauv ketones vim lub electron-dawb yam ntawm alkyl pawg. Aldehydes tsuas muaj ib qho e- pab pawg neeg pub thaum ketones muaj ob.

Vim li cas toluene reactive dua li benzene?
Toluene thiab Phenol muaj ntau reactive dua benzene vim lawv pab pawg ntxiv electron ceev rau lub nplhaib . Toluene's methyl pawg ntxiv cov electron ceev los ntawm cov nyhuv inductive inductive hauv chemistry, cov nyhuv inductive yogib qho cuam tshuam txog kev sib kis ntawm kev sib koom tsis sib xws ntawm kev sib koom ua ke ntawm cov khoom siv hluav taws xob los ntawm cov saw hlau ntawm atoms hauv cov molecule, ua rau ib tug mus tas li dipole nyob rau hauv ib daim ntawv cog l
Vim li cas imines ntau dua reactive dua aldehydes?
Txawm li cas los xij, yog tias cov tshuaj tiv thaiv tau khiav hauv cov kua qaub me me, vim tias cov imine nitrogen yog qhov yooj yim dua li carbonyl oxygen, ntau dua ntawm imine nitrogen yuav protonated dua carbonyl oxygen. Qhov no yuav ua rau cov protonated imine carbon ntau ntau electrophilic (positively polarized).
Vim li cas anhydrides ntau dua reactive dua amides?
Amides yog qhov ruaj khov tshaj plaws, thiab qhov tsis zoo tshaj plaws, vim tias nitrogen yog ib qho muaj txiaj ntsig pub dawb ntawm electrons rau pawg carbonyl. Anhydrides thiab esters tsis ruaj khov me ntsis, vim tias cov pa oxygen ntau dua electronegative dua nitrogen thiab yog qhov tsis zoo ntawm cov khoom siv hluav taws xob.
Koj puas yuav paub qhov txawv ntawm formaldehyde thiab acetaldehyde?
Formaldehyde thiab acetaldehyde tuaj yeem sib txawv los ntawm iodoform test. - Methyl ketones hnov mob nrog iodine thiab poov tshuaj hydroxide kom daj precipitate. - Acetaldehyde reacts nrog iodine thiab KOH muab sodium ntsev ntawm carboxylic acid.
Vim li cas saturated hydrocarbons tsawg reactive?
Tsawg reactivity ntawm saturated hydrocarbons yog vim muaj ib daim ntawv cog lus ntawm carbon atoms. Paraffins (alkanes) tej zaum yuav muaj cov saw ncaj los yog ceg saw isomers uas muaj cov npe niam txiv sib txawv. Vim li cas saturated hydrocarbons tsawg reactive dua unsaturated hydrocarbons?
