Both sources explain the concept similar to common organic chemistry textbooks, but they did not provide any information regarding the uses or applications of a molecular dipole's direction, nor did the google search I conducted later.
So far, two things are clear to me:
- A dipole moment is a vector, and therefore has a quantity and a direction.
- Larger dipole moment is associated with a more polar molecule. This a good enough reason to find out how large is the dipole moment.
My question is: What possible applications can knowing the direction of a molecular dipole moment have?
