In which of the following pair of compounds having same general formula ?

Options

A.
B.
C. `CH_(3)-C-=C-CH_(3) and CH_(2)=CH-CH=CH-CH=CH_(2)`
D.

Explanation

To determine which pair of compounds has the same general formula, we will analyze each option step by step.

### Step 1: Analyze Option A
1. **First Compound**: Count the number of carbon (C) and hydrogen (H) atoms.
- Carbons: 6 (C6)
- Hydrogens: 6 (H6)
- General Formula: C6H6

2. **Second Compound**: Count the number of carbon and hydrogen atoms.
- Carbons: 7 (C7)
- Hydrogens: 8 (H8)
- General Formula: C7H8

**Conclusion for Option A**: C6H6 and C7H8 do not have the same general formula.

### Step 2: Analyze Option B
1. **First Compound**: Count the number of carbon and hydrogen atoms.
- Carbons: 8 (C8)
- Hydrogens: 12 (H12)
- General Formula: C8H12

2. **Second Compound**: Count the number of carbon and hydrogen atoms.
- Carbons: 8 (C8)
- Hydrogens: 14 (H14)
- General Formula: C8H14

**Conclusion for Option B**: C8H12 and C8H14 do not have the same general formula.

### Step 3: Analyze Option C
1. **First Compound**: Count the number of carbon and hydrogen atoms.
- Carbons: 4 (C4)
- Hydrogens: 6 (H6)
- General Formula: C4H6

2. **Second Compound**: Count the number of carbon and hydrogen atoms.
- Carbons: 6 (C6)
- Hydrogens: 8 (H8)
- General Formula: C6H8

**Conclusion for Option C**: C4H6 and C6H8 do not have the same general formula.

### Step 4: Analyze Option D
1. **First Compound**: Count the number of carbon and hydrogen atoms.
- Carbons: 7 (C7)
- Hydrogens: 10 (H10)
- General Formula: C7H10

2. **Second Compound**: Count the number of carbon and hydrogen atoms.
- Carbons: 10 (C10)
- Hydrogens: 16 (H16)
- General Formula: C10H16

**Conclusion for Option D**: C7H10 and C10H16 do have a similar structure, following the general formula pattern of CnH(2n-4).

### Final Conclusion
The correct answer is **Option D** as it has compounds that follow a similar general formula pattern.
