Question

$Be{F}_2$ has zero dipole moment where as $H_{2}O$ has a dipole moment because:

• A. water is linear
• B. $H_{2}O$ is bent
• C. $F$ is more electronegative than $O$
• D. hydrogen bonding is present in $H_{2}O$

Answer 1

Answer: (B)

$H_{2}O$ is bent

$Be{F}_2$ has no dipole moment whereas $H_{2}O$ has non-zero dipole moment as the structure of $H_{2}O$ is bent due to the presence of lone pairs of electrons.
