Statement I: Dipole moment is a vector quantity and by convention it is depicted by a small arrow withtail on the negative centre and head pointing towards the positive centre.
Statement II: The crossed arrow of the dipole moment symbolizes the direction of the shift of chargesin the molecules.
In the light of the above statements, choose the most appropriate answer from the options given below:

Options

A. Both Statement I and Statement II are correct.
B. Statement I is correct but statement II is incorrect
C. Statement I is incorrect but statement II is correct.
D. Both Statement I and Statement II are incorrect.

Answer

To analyze the statements provided in the question, we will break down each statement and evaluate their correctness step by step.

### Step 1: Understanding Statement I
**Statement I:** "Dipole moment is a vector quantity and by convention it is depicted by a small arrow with tail on the negative centre and head pointing towards the positive centre."

- **Analysis:**
- The dipole moment (μ) is indeed a vector quantity.
- By convention, the dipole moment is represented by an arrow where the tail of the arrow is placed at the negative charge (or the more electronegative atom) and the head of the arrow points towards the positive charge (or the less electronegative atom).
- Therefore, this statement is **incorrect** because it incorrectly describes the direction of the arrow.

### Step 2: Understanding Statement II
**Statement II:** "The crossed arrow of the dipole moment symbolizes the direction of the shift of charges in the molecules."

- **Analysis:**
- The dipole moment arrow does symbolize the direction of the dipole, which indicates the shift in electron density towards the more electronegative atom.
- However, the statement mentions "shift of charges," which can be misleading. The dipole moment represents the shift of electron density rather than the actual movement of charges.
- Thus, this statement is also **incorrect** because it inaccurately describes what the dipole moment represents.

### Conclusion
Since both statements are incorrect, the most appropriate answer to the question is that both statements are false.

### Final Answer:
Both Statement I and Statement II are incorrect.
