3-Methylhexane is a branched hydrocarbon with two enantiomers. [2] It is one of the isomers of heptane. The molecule is chiral, and is one of the two isomers of heptane to have this property, the other being its structural isomer 2,3-dimethylpentane. The enantiomers are (R)-3-methylhexane [3] and (S)-3-methylhexane. [4]
C 3 H 5-Cl + NaF → R-F + NaCl This kind of reaction is called Finkelstein reaction . [ 2 ] However, it is also possible, for example, to produce phosphorus fluoride compounds by transhalogenating chlorine, bromine or iodine bound to phosphorus with a metal fluoride.
This is due to the abstraction of a hydrogen atom by the alkene from the hydrogen halide (HX) to form the most stable carbocation (relative stability: 3°>2°>1°>methyl), as well as generating a halogen anion. A simple example of a hydrochlorination is that of indene with hydrogen chloride gas (no solvent): [4]
In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.
C=C + X 2 → X−C−C−X (X represents the halogens bromine or chlorine, and in this case, a solvent could be CH 2 Cl 2 or CCl 4). The product is a vicinal dihalide. This type of reaction is a halogenation and an electrophilic addition.

The Suárez modification of the Hofmann–Löffler–Freytag reaction was the basis of the new synthetic method developed by H. Togo et al. [42] [43] The authors demonstrated that various N-alkylsaccharins (N-alkyl-1,2-benzisothiazoline-3-one-1,1,-dioxides) 77 are easily prepared in moderate to good yields by the reaction of N-alkyl(o-methyl ...
2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH 3) 3 CCH 2 CH(CH 3) 2. It is one of several isomers of octane (C 8 H 18 ). This particular isomer is the standard 100 point on the octane rating scale (the zero point is n -heptane ).
