M4S4 – Haloalkanes

What is the formula of 2-bromo-3-methylpentane?

Heating butan-1-ol with a mixture of sodium bromide and concentrated sulfuric acid produces 1-bromobutane. During the preparation the reaction mixture turns orange due to the formation of:

What is the main product of the reaction of 1,2-dichloroethane with a solution of ammonia in ethanol? (Under these conditions ammonia acts as a nucleophile)

What are the conditions for converting 1,2-dichlorethane into ethane-1,2-diol?

What is the name of the mechanism of the reaction between 1-bromobutane and aqueous sodium hydroxide?

Three halogenoalkanes differ in the rate with which they react with aqueous sodium hydroxide. The order of the rates of reaction is:

This procedure produces a white precipitate which dissolves easily in dilute ammonia solution: heating C₄H₉X for a few minutes with aqueous alkali, then acidifying the mixture with dilute nitric acid and adding silver nitrate. This shows that X is:

In a two step synthesis of butanoic acid what is the formula of compound X?

CH₃CH₂CH₂Br -> X -> CH₃CH₂CH₂CO₂H
