Qhov sib txawv tseem ceeb ntawm azomethines thiab ketimines yog tias azomethines yog hom thib ob aldimine uas muaj cov pa roj carbon atom hauv pawg ua haujlwm txuas nrog ib pawg hydrocarbyl thiab hydrogen atom hos cov ketimines yog hom imines uas muaj. Cov pa roj carbon atom ntawm pawg ua haujlwm txuas nrog ob pawg hydrocarbyl.
Imine tuaj yeem yog pawg ua haujlwm lossis cov tshuaj lom neeg uas muaj cov pa roj carbon-nitrogen ob daim ntawv cog lus (C=N daim ntawv cog lus). Txij li thaum qhov siab tshaj plaws ntawm cov ntawv cog lus nruab nrab ntawm nitrogen atom tuaj yeem ua tau yog 3, nitrogen atom yog sib koom ua ke rau hydrogen atom lossis ib pawg organic uas tsis yog C=N daim ntawv cog lus. Peb tuaj yeem cuam tshuam imines rau ketones thiab aldehydes los ntawm kev hloov cov pa atom hauv aldehyde lossis ketone nrog NR pawg. Yog li ntawd, muaj ob hom imines; Lawv yog cov aldimines thiab ketamines. Hauv cov no, cov aldimines muaj ib pawg R thiab hydrogen atom sib txuas rau cov pa roj carbon atom ntawm pawg N=C thaum cov ketimine muaj ob pawg hydrocarbyl txuas rau cov pa roj carbon no.
Azomethines yog dab tsi?
Azomethines yog qhov thib ob aldimines. Cov no yog imine compounds uas muaj ib pawg hydrocarbyl thiab ib pab pawg hydrogen txuas nrog cov pa roj carbon atom ntawm N=C daim ntawv cog lus thiab ib pawg hydrocarbyl txuas rau nitrogen atom.
Daim duab 01: Cov qauv dav dav ntawm Aldimine Secondary
Ketamines yog dab tsi?
Ketimines yog ib hom imines uas ob pawg hydrocarbyl txuas nrog cov pa roj carbon atom ntawm N=C daim ntawv cog lus. Muaj ob hom ketamines ua thawj ketamines thiab theem nrab ketimines.
Daim duab 02: Cov qauv dav dav ntawm lub hauv paus tseem ceeb Ketimine
Daim duab 03: Cov qauv dav dav ntawm Ketimine Secondary
Ketimines thawj zaug muaj hydrogen atom txuas rau nitrogen atom whereas cov ketimines theem nrab muaj ib pawg hydrocarbyl txuas nrog nitrogen atom.
Dab tsi yog qhov zoo sib xws ntawm Azomethines thiab Ketimines?
- Azomethines thiab ketimines yog ob hom imines.
- Thiab ob leeg muaj pawg hydrocarbyl.
Qhov txawv ntawm Azomethines thiab Ketimines yog dab tsi?
Azomethines yog cov aldimines thib ob thaum ketimines yog hom imines uas ob pawg hydrocarbyl txuas nrog cov pa roj carbon atom ntawm N=C daim ntawv cog lus. Yog li, qhov sib txawv tseem ceeb ntawm azomethines thiab ketamines yog lawv cov qauv. Azomethines yog hom thib ob aldimine uas muaj cov pa roj carbon atom hauv pawg ua haujlwm txuas nrog ib pawg hydrocarbyl thiab hydrogen atom thaum ketimines yog hom imines uas muaj cov pa roj carbon atom ntawm pawg ua haujlwm txuas nrog ob pawg hydrocarbyl. Ntxiv mus, azomethine yog ib qho tshuaj analogue ntawm aldehyde thaum lub ketimine yog ib qho tshuaj analogue ntawm ketone.
Cov lus qhia hauv qab no qhia txog qhov sib txawv ntawm azomethines thiab ketimines hauv daim ntawv tabular.
Summary – Azomethines vs Ketimines
Imine tuaj yeem yog pawg ua haujlwm lossis cov tshuaj lom neeg uas muaj cov pa roj carbon-nitrogen ob daim ntawv cog lus (C=N daim ntawv cog lus). Azomethines thiab ketimines yog ob hom imines. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm azomethines thiab ketimines yog tias azomethines yog hom thib ob aldimine uas muaj cov pa roj carbon atom hauv pawg ua haujlwm txuas nrog ib pawg hydrocarbyl thiab hydrogen atom hos cov ketimines yog hom imines uas muaj cov pa roj carbon atom. ntawm pawg ua haujlwm txuas nrog ob pawg hydrocarbyl.
