Answer -
The Lewis structure for BeH2 is as follows:
There is no lone pair at the central atom(Be) and there are two bond pairs. Hence, BeH2 is of the type AB2. It has a linearstructure.
Dipolemoments of each H–Be bond are equal and are in opposite directions. Therefore,they nullify each other. Hence, BeH2 molecule has zerodipole moment.
