1. a.Nucleophilic substitution and 1, 2-Methyl shift
2. Nucleophilic substitution reaction
3. Elimination reaction
4. Addition reaction B. a.Addition reaction b. Nucleophilic substitution reaction c. Elimination reaction d. Nucleophilic substitution and 1, 2-Methyl shift c. a. Nucleophilic substitution reaction b. Addition reaction c. Nucleophilic substitution and 1, 2-Methyl shift d. Elimination reaction D. a.Addition reaction b. Nucleophilic substitution reaction c. Nucleophilic substitution and 1, 2-Methyl shift d. Elimination reaction

Correct answer: Addition reaction B. a.Addition reaction b. Nucleophilic substitution reaction c. Elimination reaction d. Nucleophilic substitution and 1, 2-Methyl shift c. a. Nucleophilic substitution reaction b. Addition reaction c. Nucleophilic substitution and 1, 2-Methyl shift d. Elimination reaction D. a.Addition reaction b. Nucleophilic substitution reaction c. Nucleophilic substitution and 1, 2-Methyl shift d. Elimination reaction

Solution

The correct option matches the reaction types for each equation: (a) is addition across a multiple bond, (b) is nucleophilic substitution, (c) involves substitution with rearrangement via a 1,2-methyl shift, and (d) is elimination to form an alkene. So the set of classifications in option D is the right one.
