Chemical Bonding and Oxidation Numbers Quiz

Covalent bond involves the sharing of electrons between atoms.

Hydrogen typically has an oxidation number of +1 in most compounds.

Oxygen typically has an oxidation number of -2 in most compounds.

NaCl (sodium chloride) contains an ionic bond between sodium and chlorine ions.

The bond angle in a water molecule (H2O) is approximately 109.5 degrees.

CH4 (methane) has nonpolar covalent bonds.

Sulfur has a +6 oxidation state in SO3 (sulfur trioxide).

H2O (water) exhibits hydrogen bonding due to the presence of hydrogen atoms bonded to highly electronegative oxygen.

The formal charge on nitrogen in NH4+ (ammonium ion) is +1.

The shape of the SF6 (sulfur hexafluoride) molecule is octahedral.

The central atom in SF6 (sulfur hexafluoride) exhibits sp3d2 hybridization.

NH3 (ammonia) has a trigonal pyramidal shape.

H2O (water) has the highest boiling point among the given molecules due to its strong hydrogen bonding.

Chlorine has an oxidation number of +7 in HClO4 (perchloric acid).

NH4+ (ammonium ion) is an example of a coordinate covalent bond, where the shared pair of electrons comes from the nitrogen atom.
