H2O has a net dipole moment while BeF2 has zero dipole moment becausea...
**Explanation:**
The dipole moment of a molecule is a measure of the polarity of the molecule. A molecule has a net dipole moment if there is an uneven distribution of electron density within the molecule. This occurs when there is a difference in electronegativity between the atoms in the molecule and when the molecule is not symmetric.
**a) H2O molecule is linear while BeF2 is bent:**
This statement is incorrect. The H2O molecule is bent, not linear. The presence of two lone pairs of electrons on the oxygen atom causes the molecule to have a bent shape.
**b) BeF2 molecule is linear while H2O is bent:**
This statement is correct. The BeF2 molecule is linear, meaning the two fluorine atoms are directly opposite each other, resulting in a symmetrical distribution of electron density. As a result, the molecule has zero dipole moment. On the other hand, the H2O molecule is bent, with the oxygen atom pulling the electron density towards itself, resulting in an uneven distribution of electron density and a net dipole moment.
**c) Fluorine has more electronegativity than oxygen:**
This statement is incorrect. Oxygen is more electronegative than fluorine. Electronegativity is a measure of an atom's ability to attract electrons towards itself in a covalent bond. Oxygen has an electronegativity value of 3.44, while fluorine has an electronegativity value of 3.98.
**d) Beryllium has more electronegativity than oxygen:**
This statement is incorrect. Oxygen is more electronegative than beryllium. Beryllium has an electronegativity value of 1.57, while oxygen has an electronegativity value of 3.44.
Therefore, the correct answer is option 'b'. The BeF2 molecule is linear, resulting in a symmetrical distribution of electron density and zero dipole moment. The H2O molecule is bent, resulting in an uneven distribution of electron density and a net dipole moment.
