Nyob hauv chemistry, lub sij hawm amide yog qhov sib xyaw nrog cov pab pawg ua haujlwm RₙEₓNR₂, qhov twg n thiab x yuav yog 1 lossis 2, E yog qee lub caij, thiab txhua R sawv cev rau pawg organic lossis hydrogen. Nws yog ib tug derivative ntawm ib tug oxoacid RₙEₓOH nrog ib pawg hydroxy –OH hloov los ntawm ib pawg amine –NR₂.
Amide formula yog dab tsi?
6.9 Amides
Cov amides yooj yim tshaj plaws yog cov derivatives ntawm ammonia (NH3) uas ib lub atom hydrogen tau hloov los ntawm pawg acyl. Kev sib raug zoo thiab ntau ntau yog amides muab los ntawm thawj amines (R′NH2) nrog cov mis RC(O)NHR′.
piv txwv yog dab tsi?
Ib amide yog ib pawg ua haujlwm organic nrog carbonyl sib txuas rau nitrogen lossis ib qho chaw uas muaj cov pab pawg ua haujlwm no. Piv txwv ntawm amides suav nrog nylon, paracetamol, thiab dimethylformamide. Qhov yooj yim amides yog derivatives ntawm ammonia. Feem ntau, amides yog lub hauv paus tsis muaj zog heev.
Amide vs amine yog dab tsi?
Cov tshuaj muaj nitrogen atom sib koom ua ke hauv hydrocarbon moj khaum yog cais raws li amines. Cov tshuaj uas muaj nitrogen atom sib txuas rau ib sab ntawm pawg carbonyl raug cais ua amides.
Amide functional group hu ua dab tsi?
1. Nomenclature ntawm Amide Functional Group: Thawj, Secondary, thiab Tertiary Amides. "Amides" yog qhov peb hu ua amine uas muaj ib pawg carbonyl txuas. Cov pab pawg ua haujlwm amide yog rau amines li estersrau cawv.
