Direction of the Dipole moment arrow

Hi,

I know in lecture we mentioned that the arrow for the dipole moment points toward the negative partial charge with the plus sign on the positive partial charge. In the textbook, it mentions that the way I described above is the conventional method and the book will use the modern convention with the arrow pointing towards the atom with the positive partial charge...

so do we follow the convention method with the arrow pointing to the negative partial charge? Please let me know as soon as possible.

Thanks!

Sincerely,
Yashwi

That's a really good question, I had the same question too. I have just been using the arrow that points towards the most negative charge (with the plus over the positive atom), as that's how my TA has been doing it in discussions.

Dr. Lavelle has been drawing the arrow pointing to the negative end, so I'm following his conventions :)

Correct. As I discussed in class we are using the chemistry convention with the arrow pointing in the same direction the electrons are pulled.
