C. Statement -1 is True, Statement -2 is False
D. Statement -1 is False, Statmenet -2 is True

Answer

To solve the question, we need to analyze both statements provided and determine their validity.

### Step 1: Analyze Statement 1
Statement 1 claims that the carbocation `CH3CH2CH2+` is less stable than `CH3N(CH2)+`.

- **Explanation**:
- The carbocation `CH3CH2CH2+` (which is a primary carbocation) has limited stabilization options. It can only stabilize itself through hyperconjugation, which involves the interaction of adjacent C-H sigma bonds with the empty p-orbital of the positively charged carbon. In this case, it has only two alpha hydrogens available for hyperconjugation.
- On the other hand, `CH3N(CH2)+` has a nitrogen atom adjacent to the positively charged carbon. Nitrogen has a lone pair of electrons that can be donated to the carbocation through a +M (mesomeric) effect, which provides significant stabilization to the positive charge. This donation helps complete the octet for both nitrogen and the positively charged carbon, making this carbocation more stable.

### Conclusion for Step 1:
Thus, Statement 1 is **correct**: `CH3CH2CH2+` is indeed less stable than `CH3N(CH2)+`.

### Step 2: Analyze Statement 2
Statement 2 claims that carbocations with adjacent heteroatoms like nitrogen or oxygen are less stable.

- **Explanation**:
- This statement is misleading. In fact, carbocations adjacent to heteroatoms (like nitrogen or oxygen) are generally **more stable** due to the ability of these heteroatoms to donate lone pairs of electrons.
- Nitrogen can donate one lone pair, while oxygen can donate two lone pairs, both of which can help stabilize the positive charge on the carbocation. Therefore, the presence of adjacent heteroatoms typically enhances the stability of carbocations rather than decreases it.

### Conclusion for Step 2:
Thus, Statement 2 is **incorrect**: Carbocations with adjacent heteroatoms are more stable, not less stable.

### Final Conclusion:
- Statement 1 is true.
- Statement 2 is false.

### Answer:
The correct answer is that Statement 1 is true and Statement 2 is false.
