1. (a)** C4H9Cl has a number of structural isomers. Draw and name the structural formulas of an isomer of C4H9Cl that is:
- (i)** a primary isomer
(ii) a secondary isomer
(iii) a tertiary isomer.
2. (b) (i)** Identify which of these isomers will react with aqueous sodium hydroxide almost exclusively by an SN1 mechanism. Explain the symbols in the term SN1 .
- (ii)** Draw the mechanism for this reaction using curly arrows to represent the movement of electron pairs.
