ANSWER:Solution:
Here we have to show the direction of dipole moment in the given molecules.
Dipole moment: - Dipole moment arises when there is a separation of charge between the molecules. It depends on the difference in electronegativity. when an atom in a molecule undergoes unequal sharing of electrons then it is said to be polar and creates dipole moment.
Dipole moment is presented by an arrow. The arrow is directed towards the more electronegative element.
Step 1
a. H3C-Br
Here Br atom is more electronegative hence the arrow will be heading towards Br atom.
