**Reaction Mechanisms in Alcohols and Ethers**

This section involves understanding the mechanisms through which certain reactions involving alcohols and ethers proceed. Below are two reactions, followed by a list of possible mechanisms. Your task is to identify the mechanism used in each reaction by choosing from the options provided.

**Reaction 1:**
A compound with a bromine group reacts with water in the presence of aqueous acetone to form an alcohol and HBr. 

**Reaction 2:**
An epoxide reacts with HBr to form a bromohydrin intermediate.

**Mechanism Options:**

- **a = Proton transfer**
- **b = Lewis acid/base**
- **c = Electrophilic addition**
- **d = E1 Elimination**
- **e = E2 Elimination**
- **f = S<sub>N</sub>1 Nucleophilic substitution**
- **g = S<sub>N</sub>2 Nucleophilic substitution**

**Instructions:**

Match each reaction with the appropriate mechanism:

1. Reaction 1: [ ]
2. Reaction 2: [ ]

These reactions illustrate fundamental processes in organic chemistry, emphasizing the transformation of functional groups and the approach of different nucleophiles and electrophiles.

**Note:** Understanding these mechanisms is essential for predicting reaction outcomes and for the synthesis of complex molecules in organic chemistry.
