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.
Statement II :- The crossed arrow of the dipole moment symbolizes the direction of the shift of charges in the molecules.
In the light of the above statements, choose the most appropriate answer from the options given below :-
Statement II :- The crossed arrow of the dipole moment symbolizes the direction of the shift of charges in the molecules.
In the light of the above statements, choose the most appropriate answer from the options given below :-
- (A)Both Statement I and Statement II are correct.
- (B)Statement I is incorrect but Statement II is correct.
- (C)Both Statement I and Statement II are incorrect.
- (D)Statement I is correct but Statement II is incorrect.✓ Correct
Answer: (D)
Solution
Dipole moment is a vector, and by the accepted convention its arrow is drawn with the tail at the negative centre and the head pointing towards the positive centre, so the first statement is correct. The crossed arrow placed over a bond, however, marks the direction of the shift of electron density rather than a shift of charges, so describing it as a shift of charges makes the second statement incorrect. Thus the first statement is correct but the second is incorrect.
