Answer:
Bond between N and Br is non polar bond
- Nitrogen being the element of group 15 , it required only 3 electrons to complete it's octace
- and BR, element of group 17 requires only one electron to complete it's octace
- both nitrogen and br share their electrons as for forming ionic bond it requires too much energy for nitrogen to remove 3 electrons
- also here, valency of br is only one.
- both are non metal so they formed covalent bond.
