draw the major product of the following reactions

### Reaction Schemes

#### k.
**Reactants:** 
- Hydrocarbon with a triple bond (alkyne)

**Reagent:** 
- \( \text{Cl}_2 \) (Chlorine)

**Description:**
The reaction involves the addition of chlorine (\( \text{Cl}_2 \)) to a triple-bonded alkyne, resulting in the formation of a chlorinated hydrocarbon.

---

#### l.
**Reactants:**
- Hydrocarbon with a triple bond (alkyne)

**Reagent:**
- \( \text{HBr (excess)} \) (Hydrobromic acid)

**Description:**
Excess hydrobromic acid (\( \text{HBr} \)) reacts with an alkyne, leading to the addition of bromine across the multiple bonds and forming a dibromo alkane.

---

#### m.
**Reactants:**
- Alkyne with a branching at the terminal carbon

**Reagents:**
- \( \text{H}_2\text{O} \) (Water)
- \( \text{H}_2\text{SO}_4 \) (Sulfuric Acid)
- \( \text{HgSO}_4 \) (Mercuric Sulfate)

**Description:**
In the presence of sulfuric acid and mercuric sulfate, water adds across the triple bond of an alkyne. This hydration reaction typically results in a ketone formation.

---

#### n.
There appears to be no visible molecule or reagent. It may be intended for another example or detail not shown in the image.

---

These reaction schemes illustrate common addition reactions involving alkynes that result in the formation and transformation of various functional groups.
