About this deal

n-алкани, су припадници хомологог низа. Рачвасти низови су са друге стране структурни изомери нормалног низа па их IUPAC-ова номенклатура тако и третира. Пре стандардизације номенклатуре, рачвасти алкани су добијали префиксе (изо-, нео-, terc-...) док је основни назив потицао од укупног броја угљеника у молекулу.

C nH 2n+2, са органични химични съединения, принадлежащи към класа на ацикличните наситени въглеводороди. Най-простият представител е метанът. Редицата продължава неограничено. Алканите се срещат в природата като съставна част на нефта, но могат да се получат и чрез химичен синтез. Određivanje broja supstituentima i vezama s pripadajućim lokantima. Ako ima više supstituenata/dvostrukih veza iste vrste, dodaje se prefiks koji pokazuje količinu istovrsnih supstituenata/dvostrukih veza ( di – 2 tri – 3 tetra – 4 a zatim kao za ugljične lance s dodanim 'a') Naziv "neo-pentan" je iznimka - inače svi razgranati strukturni izomeri nekog alkana imaju prefiks -izo.

Zaradi večje stabilnosti sekundarnih in terciarnih prostih radikalov se halogeni raje vežejo na sekundarne in terciarne ogljikove atome. Značilen primer je monobromiranje propana. imena alkil grupa se stavljaju ispred imena alkana a njihov položaj se označava brojem ugljenikovog atoma na koji su vezani.

Amidi s dodatnim substituentima na dušikovu atomu tretiraju se slično aminima: redaju se abecedno uz prefiks veznog mjesta N: HCON(CH 3) 2 je N, N-dimetilmetanamid.Dragan and his colleague were the first to report about isomerization in alkanes. [28] Isomerization and reformation are processes in which straight-chain alkanes are heated in the presence of a platinum catalyst. In isomerization, the alkanes become branched-chain isomers. In other words, it does not lose any carbons or hydrogens, keeping the same molecular weight. [28] In reformation, the alkanes become cycloalkanes or aromatic hydrocarbons, giving off hydrogen as a by-product. Both of these processes raise the octane number of the substance. Butane is the most common alkane that is put under the process of isomerization, as it makes many branched alkanes with high octane numbers. [28] Other reactions [ edit ] Vsi alkani s kisikom popolnoma zgorijo v ogljikov dioksid in vodo: C nH 2n+2 + (1,5n+0,5)O 2 → (n+1)H 2O + nCO 2
