What is the role of sodium in wurtz reaction?
One electron from the metal is transferred to the halogen to produce a metal halide and an alkyl radical.R-X + M → R• + M+X− The alkyl radical then accepts an electron from another metal atom to form an alkyl anion and the metal becomes cationic. This intermediate has been isolated in a several cases.R• + M → R−M+ The nucleophilic carbon of the alkyl anion then displaces the halide in an SN2 reaction, forming a new carbon-carbon covalent bond.R−M+ + R-X → R-R + M+X−
What reagents are used to convert alcohols to alkyl halides?
HX X being a halide. Which makes it basic
Why hydrogen bromide is electrophile?
hydrogen bromide is not the electrophile its bromide ion may act as the nucleophile, in alkyl halide the alkyl group may act as an electrophile.
Is it possible for an alkyl halide to undergo sn1 and also sn2 reactions?
Yes an alkyl halide can undergo both Sn1 and Sn2 reactions - it just depends on what kind of alkyl halide it is. Methyl halides such as CH3Br/CH3Cl/CH3I, etc. are most suitable for Sn2 reactions because they are less sterically hindered by R-groups (they are not "bulky"). This allows for easy attack by the nucleophile. Primary alkyl halides (RCH2X) are also most suitable for Sn2 because of the same reason above Secondary alkyl halides can undergo both Sn1 and Sn2 reactions, this depends on other factors such as solvent and leaving group and nucleophile. If the solvent is polar aprotic, the reaction will go Sn2, if polar protic - Sn1. Tertiary alkyl halides (alkyl halides with 4 r-groups) do not go Sn2 because they are bulky and the R-groups stabilize the carbocation by hyperconjugation and inductive effect.
What is the chemical formula of detergent from soda ash and Alkyl benzene sulphonic acid?
Discuss the chemical reaction between soda ash and alkyl benzene sulphonic acid
Why alcoholic medium in reaction KCN and alkyl halide?
alcoholic medium is necessary because if it is aqueous then CN- will hydrolysis water to form HCN and OH-.Therefore there will be two nucleophile in aqueous CN- AND OH-.
During a reaction the OH group of an alcohol is replaced by a chlorine atom. Which type of reaction occurred?
An alkyl halide is obtained.
Why primary alkyl halide are not syntesized using Sn1 reaction?
as order of reactivity of sn1 reaction is 3>2>1 , we do not synthesise primary alkyl halide using sn1 reation. as there is no pushing from other carbon atoms, it is difficult for the X part of RX to separate itself.
How many distinct alkene products are possible when a alkyl halide undergoes E2 elimination?
It depends on the structure of the alkyl halide. Although generally E1 elimination would predominate in cases where the alkyl halide is highly substituted (and more products are possible).
What are other examples of alkyl halide?
an example of Alkyl halides is R-X ( x represents any halogen) C2F4 is Teflon it is an example of Alkyl Halides

Why must the crude alkyl halide product be dried carefully with anhydrous calcium chloride before distillation?
crude alkyl halide in liquid state is too hygroscopic to cath fire even at little temperature! but in solid form its hygroscopic nature lowers decreasing the danger mentioneed above! that's y crude alkyl halide producs should be dried before distillation!
What type of compound is ch3-ch2-ch2-cl?
It is an haloalkane (aka alkyl halide).
Why hydrogen bromide is electrophile?
hydrogen bromide is not the electrophile its bromide ion may act as the nucleophile, in alkyl halide the alkyl group may act as an electrophile.

the agx will presipate and one ether will produce
