Chemical Bonding and Molecular Structure - Result Question 35

####36. H2O has a non zero dipole moment while BeF2 has zero dipole moment because

[1989]

(a) H2O molecule is linear while BeF2 is bent

(b) BeF2 molecule is linear while H2O is bent

(c) Fluorine has more electronegativity than oxygen

(d) Beryllium has more electronegativity than oxygen.

Topic 4: VSEPR Theory and Hybridisation

Show Answer

Solution:

  1. (b) BeF2 is linear and hence has zero dipole moment while H2O, being a bent molecule, has a finite or non-zero dipole moment.
