Amide en amine

Amines are molecules that contain carbon-nitrogen bonds. The nitrogen atom in an amine has a lone pair of electrons and three bonds to other atoms, either carbon or hydrogen. Various nomenclatures are used to derive names for amines, but all involve the class-identifying suffix -ine as illustrated here for a few simple examples Het belangrijkte verchil tuen Amide en Amine i dat de Amide i een groep chemiche toffen en Amine i een organiche verbinding die een derivaat van ammoniak i. amide Een amide (of of), ook bekend al een zuuramide, i een verbinding met de functionele groep RnE (O) xNR'2 (R en R 'verwijzen naar H of organiche groepen). Het meet gebruikelijk zijn carboxamiden (organiche amiden) (n = 1, E = C, x = 1. Een amide is: Een functionele groep waarin een stikstofatoom gebonden is aan een atoom met een hoge partiële lading. Net als bij ether en alcohol wordt de naam amide vaak beperkter gebruikt als aanduiding voor een carbonzuuramide, de hieronder genoemde groep. Ook sulfonamiden behoren tot de amiden. Een functionele groep bestaande uit een koolstofatoom waaraan zowel een dubbel gebonden zuurstofatoom als een stikstofatoom gebonden zijn. Het zuurstofatoom heeft geen bindingen meer.

Amine vs. Amide. Als je ooit goed hebt gelet op je scheikunde-leraar, dan heb je misschien wel gehoord van de termen amides en amines. Vanwege hun schuine gelijkenis in spelling, slechts een letter die verschilt van de andere, zijn beide termen onderworpen aan veel verwarring Amine versus Amide . Aminen en amiden zijn beide stikstofhoudende organische verbindingen. Hoewel ze op elkaar lijken, zijn hun structuur en eigenschappen heel verschillend. Amine. Aminen kunnen worden beschouwd als organische derivaten van ammoniak. Aminen hebben stikstof gebonden aan een koolstofatoom Een amine heeft enkel een R-NH2 groep (zie ook weer het voorbeeld) Beiden hebben totaal verschillende eigenschappen. Een amine is basisch en lost dus op in verdund zuur. Een amide is niet basisch, en lost dus niet op in zuur midden. Er zijn uiteraard ook verschillen wat de reactiviteit betreft, maar ik neem dat dit te ver gaat

Het belangrijkste verschil tussen amine en amide is de aanwezigheid van een carbonylgroep in hun structuur; aminen hebben geen carbonylgroepen vastgemaakt aan het stikstofatoom terwijl amiden een carbonylgroep gekoppeld aan een stikstofatoom hebben A triruthenium cluster catalyzes the reaction of secondary amides with hydrosilanes, yielding a mixture of secondary amines, tertiary amines, and silyl enamines. Production of secondary amines with complete selectivity is achieved by the use of higher concentration of the catalyst and bifunctional hydrosilanes such as 1,1,3,3-tetramethyldisiloxane followed by acidic workup Een amine is een functionele groep bestaande uit een stikstofatoom met daaraan gebonden drie koolstof- en/of waterstofatomen.Afhankelijk van het aantal koolstofatomen spreekt men van een: primair amine: aan het stikstofatoom is één alkylgroep gebonden (en twee waterstofatomen).; secundair amine: aan het stikstofatoom zijn twee alkylgroepen gebonden (en één waterstofatoom) In organic chemistry, an amide, also known as an organic amide or a carboxamide, is a compound with the general formula RCNR′R″, where R, R', and R″ represent organic groups or hydrogen atoms. The amide group is called a peptide bond when it is part of the main chain of a protein, and isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. It can be viewed as a derivative of a carboxylic acid RCOH with the hydroxyl group -OH.

Re: Van Amide naar amine Lol een heel expiriment voor een voorschrift, lijkt me beetje overdreven, ik schrijf het wel op en hoop dat de docent het goed vind xD Omhoo Amides and amines have different structures and properties, so the distinction is actually very important. Organic-nitrogen compounds containing metals are also called amides, so if you see a molecule that has a nitrogen and either a carbonyl group or a metal next to that nitrogen, then you know that molecule should be an amide instead of an amine

Many derivatizations of amines lead in fact to amides, which have a better behavior in the chromatographic column compared to amines (see Section 19.4). However, amide derivatization still may be needed. Although the polarity of the hydrogen in -C(O)-NH-group is not high, its elimination may still improve the GC separations amine: [noun] any of a class of basic organic compounds derived from ammonia by replacement of hydrogen with one or more monovalent hydrocarbon radicals — compare amide 2 When the amide is derived from a primary or secondary amine, the substituents on nitrogen are indicated first in the name.

See also secondary amine, tertiary amine This is not an amine but is a salt. If one of the groups on the nitrogen is a carbonyl group, then the molecule is called amide. This has very different properties. Amines are used a lot in chemistry. Since the nitrogen has a lone pair, it can do many reactions. It can take protons away from some acids.
