### Organic Chemistry Reaction Question

**Question 13:**

Which of the following is the major product of the reaction?

**Reactants:**

- Ethyne (\( \text{CH}_3C \equiv \text{CH} \))
- Excess Hydrobromic Acid (\( \text{HBr} \))

**Possible Products:**

a) \(\text{CH}_3-\text{CH}=\text{CHBr}\)

b) \(\text{CH}_3-\text{CHBr}-\text{CH}_2\text{Br}\)

c) \(\text{CH}_3-\text{CBr}_2-\text{CH}_3\)

d) \(\text{BrCH}_2-\text{CH}_2-\text{CH}_2-\text{Br}\)

e) \(\text{CH}_3-\text{CH}_2-\text{CHBr}-\text{CH}_2\text{Br}\)

f) \(\text{CH}_2=\text{CH}-\text{CH}_2\text{Br}\)

### Explanation:

This question concerns the addition of hydrobromic acid to ethyne. When ethyne reacts with excess HBr, the addition follows Markovnikov's rule, leading to the major product. Students need to determine which structure represents the result of this reaction.

**Key Concepts:**
- Electrophilic addition reactions in alkenes and alkynes.
- Markovnikov's rule, which predicts the formation of the most stable carbocation intermediate.
- Reactivity of alkynes with hydrogen halides in excess.
