AS Haloalkane Reactions Sub/Elimination
Help appreciated on the following questions:
1) Bromoethane can undergo further substitution. Write an overall equation for the reaction between bromoethane and bromine in which dibromomethane is formed. ( I know the reactions for chlorine not sure are they similar and I understand how to draw the mechanism)
2) CH3Br + 2NH3 ---) CH3NH2 + NH4Br
Name the organic product of this reaction (I presume it is an amine/amide)
3)Ethanenitrile can be made by reacting chloromethane with potassium cyanide:
i) write and equation for this reaction
ii) Name the mechanism for this reaction
iii) Explain in terms of bond enthalpies why bromoethane reacts faster than chloromehtane with potassium cyanide
4) chloromethane can react with ammonia to produce a primary amine:
i) what feature of the chloromethane molecule make it susceptible to attack by an ammonia molecule?
ii)Name the amine produced
iii) outline a mechanism for this reaction

iii) outline a mechanism for this reaction
1) Br behaves exactly the same way as Cl so if you know the mechanism with Cl, just draw it out but replace Cl with Br
2)CH3NH2 is the organic compound
3i) CH3Cl + KCN ------> CH3CN + KCl
ii) Nucleophilic substitution
iii)br bond is longer and weaker than cl bond thus requires less energy to break
4i)
ii) CH3NH2 aminomethane
iii) nucleophilic substitution mechanism

What are your thoughts on Q3 and Q4? I can help you understand if you say what your problem is, rather than just doing your homework for you.
Anyway, for Q3 you need to think about the formulae of the compounds: chloromethane is and potassium cyanide is . Do you know what the formula for ethanenitrile is (if not, can you work it out?) and thus write an equation for the reaction?

lol i did his homework for him since it aids my revision for unit 3 chem retake.

Is it aminoethane or methylamine or are both the same?
I am prepared to learn at the same time so can take it step by step

Original post by spook2575
both exactly the same
They're totally different and not the same at all
