CE ÎNSEAMNĂ AMIDE ÎN ENGLEZĂ?
Amidă
O amidă, de asemenea cunoscută ca o amidă a acidului, este un compus cu gruparea funcțională RnE (O) xNR'2 (R și R 'se referă la H sau grupări organice). Cele mai obișnuite sunt amidele organice (n = 1, E = C, x = 1), dar sunt cunoscute multe alte tipuri importante de amide incluzând fosforamida (n = 2, E = P, și sulfonamide (E = S, x = 2). Termenul amidă se referă atât la clasele de compuși, cât și la gruparea funcțională (RnE (O) xNR'2) în acei compuși. Amida se poate referi, de asemenea, la baza conjugată a amoniacului (anionul H2N-) sau a unei amine organice (un anion R2N-). Pentru discutarea acestor "amide anionice", vezi amide metalice # Amide metalice alcaline. Restul acestui articol se referă la simțul carbonil-azot al amidei.
Definiția amide în dicționarul Engleză
Prima definiție a amidei din dicționar este orice compus organic care conține gruparea funcțională -CONH2. Alte definiții ale amidei constau în, conținând sau interesate de grupul -CONH2. Amida este, de asemenea, un compus anorganic având formula generală Mx, în care M este un atom de metal.
