In Ammonia molecule the bond angle is `107^@` and in water molecule it is `104^@35`, although in both the central atoms are sp3 hybridized. Explain.

Explain why BeH_2 molecule has a zero dipole moment although the Be-H bonds are polar.

Display electron distribution around the oxygen atom in water molecule and state shape of the molecule, also write H-O-H bond angle.

The bond angle in H_(2)O molecule is less than that of NH_(3) molecule because__________.

Which type of hybridization is present in ammonia molecule? Write the geometry and bond angle present in ammonia.

Water molecule is very polar.Polar end of molecule attracts opposite charges on another water molecule (actslike magnet). How will you explain this property of water with reference to upward movement of water? Comment on the, upward movement of water given the intermolecular hydrogen bonding in water.

Predict the shape and bond angles in the pollowing molecules: a. CF_4 b. NF_3 c.HCN d. H_2 S

Central metal atom or ion bonded to fixed number of ions or molecules is known as _______.

Although both CO_2 and H_2O are triatomic molecules, the shape of H_2O molecules is bent while that of CO_2 is linear. Explain this on the basis of dipole moment.
