The structure of a halogenoalkane containing bromine is shown in Figure 1.
Figure 1
State the colour of the precipitate formed in the reaction between the halogenoalkane in Figure 1 in part (a) and acidified silver nitrate, AgNO3.
The compound drawn in Figure 1 in part (a) is reacted with alcoholic potassium cyanide, KCN. The reaction is heated under reflux.
Draw the product of this nucleophilic substitution reaction.
The halogenoalkane drawn in Figure 2 contains a chlorine atom instead of a bromine atom. This halogenoalkane is reacted under the same conditions outlined in part (c).
Figure 2
The reaction for a halogenoalkane containing bromine would be faster than if the compound in Figure 2 was used. Briefly explain why this reaction would be faster.
