halogenoalkane to amine conditions

An explanation of the terms nucleophile and nucleophilic substitution, together with the general mechanisms for these reactions involving halogenoalkanes. Look at the strengths of various bonds (all values in kJ mol-1). Some syllabuses try to make things simpler by restricting you to just one of the two mechanisms.
Again, a lone pair on the approaching hydroxide ion forms a bond with the + carbon and, in the process, the electrons in the carbon-bromine bond are forced entirely onto the bromine to create a bromide ion. The reactions between secondary or tertiary halogenoalkanes and hydroxide ions - the SN1 mechanism
Understanding Chemistry. NUCLEOPHILIC SUBSTITUTION MECHANISMS MENU. Types of halogenoalkanes . . . Describes what is meant by primary, secondary and tertiary halogenoalkanes. Essential knowledge if you are to make sense of everything else in this section. What is nucleophilic substitution? . . . Includes
You could write the full equation rather than the ionic one, but it slightly obscures what's going on: The bromine (or other halogen) in the halogenoalkane is simply replaced by an -OH group - hence a substitution reaction. In this example, propan-1-ol is formed. The mechanism. Here is the mechanism for the reaction
For example, using 1-bromoethane as a typical primary halogenoalkane: An alcohol is produced together with hydrobromic acid. Be careful not to call this hydrogen bromide. Hydrogen bromide is a gas. When it is dissolved it in water (as it will be here), it's called hydrobromic acid. The mechanism. The mechanism involves
19 Nov 2006
Reactions involving halogenoalkanes (haloalkanes, alkyl halides) and silver nitrate solution. the quicker the precipitate appears, the more reactive the halogenoalkane. The halide ion is formed in one of two ways, depending on the type of halogenoalkane you have present - primary, secondary or tertiary.
Facts and mechanisms for the reactions between halogenoalkanes and cyanide ions - nucleophilic substitution. If you want the mechanisms explained to you in detail, there is a link at the bottom of the page. The reaction of primary For example, using 1-bromopropane as a typical primary halogenoalkane: You could
Facts and mechanisms for the reactions between halogenoalkanes and ammonia - nucleophilic substitution. If you are interested in further substitution reactions, you will also find a link to a separate page dealing with these. We'll talk about the reaction using 1-bromoethane as a typical primary halogenoalkane.
