Which of the following statements (s) i/are true?
I. Compound containing carbon and hydrogen only are called homocarbons.
II. Hydrocarbon is termed saturated if it contains only carbon carbon single bonds.
III. Paraffin means greater affinity.
Choose the correct option.

Options

A. Only III
B. Only II
C. II and III
D. All the these

Answer

To determine which of the given statements are true, let's analyze each statement step by step.

### Step 1: Analyze Statement I
**Statement I:** "Compounds containing carbon and hydrogen only are called homocarbons."

- This statement is **incorrect**. The correct term for compounds that contain only carbon and hydrogen is **hydrocarbons**, not homocarbons. The term "homocarbons" is not commonly used in organic chemistry.

### Step 2: Analyze Statement II
**Statement II:** "Hydrocarbon is termed saturated if it contains only carbon-carbon single bonds."

- This statement is **correct**. Saturated hydrocarbons are indeed those that contain only single bonds between carbon atoms. Examples include alkanes like ethane (C2H6) and propane (C3H8).

### Step 3: Analyze Statement III
**Statement III:** "Paraffin means greater affinity."

- This statement is **incorrect**. The term "paraffin" actually refers to saturated hydrocarbons, which are characterized by their low reactivity and thus have **less affinity** for reagents. The word "paraffin" comes from the Latin "parum affinis," meaning "little affinity," indicating that these compounds are less reactive.

### Conclusion
Based on the analysis:
- Statement I is **false**.
- Statement II is **true**.
- Statement III is **false**.

Thus, the only true statement is Statement II.

### Final Answer
The correct option is that only Statement II is true.
