Alkyl iodides cannot be prepared directly by iodination of alkanes because iodine is not a good enough electrophile to react with an alkane under typical reaction conditions. Alkyl iodides are usually prepared indirectly by reacting an alkyl halide with a soluble iodide salt in the presence of a mild oxidizing agent.

Why Methane can't be prepared by wurtz synthesis?

Because in wurtz synthesis you have two alkane molecules which react with each other, for instance two iodomethane groups and sodium. You would get sodium iodide and two groups of methane, which equals ethane.


How you prepared tetraethyl lead and tetramethyl lead from alkyl halide?

Tetraethyl lead can be prepared by reacting ethyl chloride with sodium metal and lead chloride, while tetramethyl lead can be prepared by reacting dimethyl mercury with methyl iodide and lead oxide. Both processes involve the reaction of alkyl halides with lead compounds to form the desired organolead compound. It's important to note that these processes are hazardous due to the toxicity of organolead compounds and should be conducted by trained professionals in a well-equipped laboratory with proper safety measures in place.


Is toluene to aniline possible by gabriel reaction?

No, toluene cannot be directly converted to aniline by the Gabriel synthesis. The Gabriel synthesis involves the reaction of an alkyl halide with potassium phthalimide to form an alkyl phthalimide intermediate, which is then converted to the primary amine through a nucleophilic substitution reaction. Toluene does not contain a suitable leaving group for this type of reaction.


What is the pH of an Alkyl Halide?

The pH is almost always on acidic side (i.e. pH < 7). The reason being, some of the alkyl halides tend to decompose via beta hydride elimination process generating hydro-halo acids that impart acidity, e.g. tertiarybutyl chloide decomposes to produce HCl or hydrochloric acid.


How do you prepare Gilman reagent?

Gilman reagents are prepared by reacting a lithium alkyl or aryl compound with copper(I) iodide in diethyl ether under anhydrous conditions. This reaction is typically carried out at low temperatures to prevent side reactions. The resulting Gilman reagent is then used in various organic transformations, particularly in carbon-carbon bond forming reactions.

What is Alkyl phenol ethoxlate?

Surfactants that are prepared by reaction of ethylene oxide with the appropriate alkyl phenol. These surfactants are cheap to produce but suffer from biodegradability and potential toxicity.


What would be the effect of carrying out the sodium iodide in acetone reaction with the alkyhalides using an iodide solution half as concentrated?

A reaction with alkyl halides in NaI with acetone is by the Sn2 mechanism. The rate for an Sn2 mechanism is directly proportional to the concentration of the nucleophile: rate = k[nucleophile][alkylhalide] If the iodine solution (the nucleophile) is half as concentrated, then the rate will also be halved. rate = k [nucleophile]/2 [alkyl halide]


Why does 1-chlorobutane give a precipitate while I-iodopropane does not when reacted with sodium iodide in acetone even though both are primarily alkyl halide?

1-Chlorobutane gives a precipitate when reacted with sodium iodide in acetone because it undergoes an SN2 reaction, where the iodide ion displaces the chloride ion, forming a less soluble product that precipitates out of the solution. In contrast, i-iodopropane does not precipitate because it is a tertiary alkyl halide, which typically undergoes an SN1 mechanism; this reaction does not produce a solid precipitate. The difference in reactivity and solubility of the resulting products accounts for the observed precipitate formation.


What is alkylating agents?

An alkylating agent is a compound that's capable to replace a hydrogen for an alkyl group to a specific place on a molecule. Alkylating agents attacks mostly on a nitrogen, oxygen or sulfur. Common alkylating agents are: Methyl iodide(or other haloalkanes), dimethylsulfate and some carboxylic acid alkyl esters.

What is Zeisel's method?

Zeisel's method is used to estimate the alkoxy linkages in an organic compound. In this method the organic compound containing alkoxy group is treated with hydrogen iodide and the alkyl halide formed is further treated with silver nitrate to precipitate silver iodide In this reaction only hydrogen iodide can be used because it consists of an ionic bond, while HF, HCl, HBr contain covalent bond where an iodide ion is liberated which forms a precipitate with silver nitrate. The silver iodide can be weighed and from its weight the number or alkoxy group can be estimated.

How can one determine the classification of alkyl halides as primary, secondary, or tertiary?

Alkyl halides can be classified as primary, secondary, or tertiary based on the number of carbon atoms directly bonded to the carbon atom that is attached to the halogen. In a primary alkyl halide, there is one carbon atom bonded to the carbon-halogen bond. In a secondary alkyl halide, there are two carbon atoms bonded to the carbon-halogen bond. In a tertiary alkyl halide, there are three carbon atoms bonded to the carbon-halogen bond.


Why alkyl halide cannot be prepared by direct treatment of iodine and hydrocarbon?

Direct reaction of hydrocarbon with iodine is reversible because of formation HI which is reducing agent. Hence the reaction must be carried in the presence of oxidization agent like HNO3 to nutralize the HI formed.
