The longest possible main alkane chain is used; therefore 3-ethyl-4-methylhexane instead of 2,3-diethylpentane, even though these describe equivalent structures. The di-, tri- etc. prefixes are ignored for the purpose of alphabetical ordering of side chains (e.g. 3-ethyl-2,4-dimethylpentane, not 2,4-dimethyl-3-ethylpentane).
3-Ethylpentane (C 7 H 16) is a branched saturated hydrocarbon. It is an alkane , and one of the many structural isomers of heptane , consisting of a five carbon chain with a two carbon branch at the middle carbon.
Isopropyl group Methyl group. In organic chemistry, an alkyl group is an alkane missing one hydrogen. [1] The term alkyl is intentionally unspecific to include many possible substitutions.
The permethylated derivative of tren has the formula N(CH 2 CH 2 NMe 2) 3. "Me 6 tren" forms a variety of complexes but, unlike tren, does not stabilize Co(III). Related amino-triphosphines are also well developed, such as N(CH 2 CH 2 PPh 2) 3 (m.p. 101-102 °C). This species is prepared from the nitrogen mustard N(CH 2 CH 2 Cl) 3. [7]
3-Ethyl-3-pentanol, also known as 3-ethylpentan-3-ol, is a tertiary alcohol with the molecular formula C 7 H 16 O. It reacts with chromic acid by first dehydrating to an olefin 3-ethyl-2-pentene, and then by converting the double bond to an epoxide. [2] Perfluorination affords perfluorotriethylcarbinol, a powerful uncoupling agent.
In organic chemistry, an ethyl group (abbr. Et) is an alkyl substituent with the formula −CH 2 CH 3, derived from ethane (C 2 H 6). Ethyl is used in the International Union of Pure and Applied Chemistry's nomenclature of organic chemistry for a saturated two-carbon moiety in a molecule, while the prefix "eth-" is used to indicate the presence ...
3-Methylpentane is a branched alkane with the molecular formula C 6 H 14. It is a structural isomer of hexane composed of a methyl group bonded to the third carbon atom in a pentane chain. It is of similar structure to the isomeric 2-methylpentane , which has the methyl group located on the second carbon of the pentane chain.
