Substitution reaction is a reaction in which an atom, ion or guggus substitutable for (replace) atoms, ions or other groups. Substitution reactions of alkyl halides, alkyl halides called leaving group (leaving group) a term that means any group that can digeserdari bond with a carbon atom. In practical terms only Cl, Br, I was pretty good leaving group, making it useful in substitution reactions.
Substitution process generally occurs c2h5oh in species nucleophile (nucleus lover / lover positive core) and elektofil species c2h5oh (electrons lover / lover negative core). A nucleophile is a species of unity interested in anything positive center. c2h5oh So a nucleophile is a Lewis base. While an electrophile is any species that is interested in a little market c2h5oh center of the negative. So an electrophile is a Lewis acid. An electrophilic substitution reaction occurs because of the species that are attracted towards the electronegative and electron-rich atoms.
Chloroform or triklorometan have CHCl3 structure and molecular weight of 119.39 g / mol and composition includes 10.05% C, 0.84% H, and 89.10% Cl. Chloroform is also called haloform caused by bromine and chlorine also reacts with methyl ketones, which produce each bromoform (CHBr 3) and chloroform (CHCl 3). It is referred to the CHX 3 or haloform, the reaction is often called the haloform reaction.
2 Drugs
Halocarbons such as chloroform c2h5oh example compounds are easy to make, chlorinated methane created by the chlorination of methane. Chloroform c2h5oh (CHCl 3), all is not soluble in water, but it is an effective solvent for organic compounds.
In making or synthesizing chloroform to note a few things, namely the presence of oxygen from the air and the sunlight slowly oxidized chloroform can be phosgene (highly toxic gas), then to prevent the occurrence of phosgene was then chloroform, stored c2h5oh in brown bottles were filled and containing 0.5 - 1% ethanol (to bind the event of phosgene).
Chloroform compounds are compounds that bind haloalkanes three halogen atoms chlorine (Cl) at its C chain. Chloroform compounds can be made with basic ingredients such as organic compounds that have a methyl group (CH 3) attached to the C carbonyl or hydroxy C atom reagent reacted with halogens (Cl 2). Some compounds can form chloroform and other haloform c2h5oh compounds are ethanol, 2-propanol, 2-butanol, ethanol, propanone, 2-butanone.
The structure of haloalkane compound formed from halogenated process consists of a carbon-halogen bond sigma formed by mutual orbital overwrite a halogen c2h5oh atom and a carbon atom hybrid orbitals. A halogen to form a covalent bond and therefore there is no bond angles around this atom. However, carbon using the same type of hybrid c2h5oh orbitals to bind halogen, hydrogen or other carbon atoms.
This experiment was conducted to determine the formation of compounds of chloroform (CHCl 3) of chlorine and acetone through electrophilic substitution reaction. Where the electrophilic c2h5oh substitution reaction c2h5oh is due to species that are attracted towards the electronegative and positive charged atoms.
In the experiment begins by reacting a compound of chlorine (CaOCl 2) which is a white powder (solid) as much as 100 grams with 500 mL of water into a round bottom flask as she rocked back and forth to form a perfect c2h5oh suspension. The addition of this water is used to dissolve the chlorine and chlorine also extend surface c2h5oh and reduce evaporation of distillate .In this mixing process produces calcium hydroxide (Ca (OH) 2) which is alkaline and Cl 2. Reaction: CaOCl 2 + H 2 O à Ca (OH) 2 + Cl 2
Furthermore, the above solution is distilled and acetone added little by little through the funnel as much as 5 mL while shaken to reasksinya berlangsng perfectly with Cl 2 derived from mixing chlorine and water to form acetyl chloride and addition of acetone in this experiment produces a froth.
The addition of acetone serves as a medium in order to terbe ntukny a haloform reaction. in addition, the function of acetone c2h5oh is sebaga i solvent, in this case the chlorine to dissolve solids.
The next process is to do a distillation flask containing pure chloroform. The process is done by installing a round bottom flask in a distillation set of tools and then heated with a small flame so that the evaporation process is complete. The resulting steam will go through the condenser so that the cooling and will come out as distillate form chloroform.
Distillate which came out at a temperature of 60 to 63 0 C which is the boiling point of the compound chloroform dri accommodated in a closed flask no contamination to the environment and prevent the chloroform does not evaporate because of the nature of kl
