Chemical Bonding & Molecular Geometry

Which type of chemical bond involves the complete transfer of electrons from one atom to another?

According to VSEPR theory, which shape corresponds to a molecule with four bonding pairs and one lone pair of electrons around the central atom?

Which of the following molecules is nonpolar despite containing polar bonds?

What type of intermolecular force is primarily responsible for the high boiling point of water compared to molecules of similar size?

In a molecule of ammonia ($NH_3$), the polarity arises mainly because:

Which of the following statements correctly compares ionic and covalent bonds?

A molecule with symmetrical geometry and identical surrounding atoms will always be nonpolar.

London dispersion forces can occur between nonpolar molecules and are the weakest type of intermolecular force.

In VSEPR theory, lone pairs of electrons occupy more space than bonding pairs, affecting molecular shape.
