What is the order of reactivity of HCl, HBr and HI with alcohols?

Explanation

To determine the order of reactivity of HCl, HBr, and HI with alcohols, we need to consider the strength of the acids and how they interact with alcohols during the reaction process.

### Step-by-Step Solution:

1. **Understanding the Reaction**: When alcohols react with hydrogen halides (HX), they form alkyl halides. The general reaction can be represented as:
\[ R-OH + HX \rightarrow R-X + H_2O \]
