"BeH2 molecule has zero dipole moment although the Be-H bonds are polar." Explain this sentence on the basis of the concept of dipole moment.
Asked by Topperlearning User | 9th Oct, 2014, 08:42: AM
Expert Answer:
The BeH2 molecule is linear with (H-Be-H) bond angle equal to 180o.
Although the Be-H bonds are polar due to the difference in the electronegativities of Be and H atom, the bond polarities cancel each other.
As a result the resultant dipole moment is zero.
