Explain why the BeH 2 molecule has a zero dipole moment although the Be–H bonds are polar.

Options

  1. ABeH 2 has a zero dipole moment because the electronegativity of hydrogen is greater than that of beryllium, re
  2. BBeH 2 has a zero dipole moment because it is a linear molecule, and the bond dipoles point in opposite directi
  3. CBeH 2 has a zero dipole moment because it is an ionic compound with no bond dipoles.
  4. DBeH 2 has a zero dipole moment because the bond angles in the molecule result in a symmetrical charge distribu

Correct answer

B. BeH 2 has a zero dipole moment because it is a linear molecule, and the bond dipoles point in opposite directi

Step-by-step solution

Correct Option is : (B) BeH 2 has a zero dipole moment because it is a linear molecule, and the bond dipoles point in opposite directions, effectively canceling each other.
