44 Given the equation for a reaction: C4H10 + Cl2 → C4H9Cl + HCl Which type of reaction is represented by the equation? (1) addition
(2) substitution
(3) fermentation
(4) polymerization
Solution: In this reaction hydrogen is substituted by chlorine if we look from the left side (reactants) to the right side (products). This reaction is substitution. Generally, if we see an alkane (CnH2n+2 with X2, where X is halogen), the reaction is substitution.
