Q:

What are some binary molecular compounds?

A:

Quick Answer

Some examples of binary molecular compounds are hydrofluoric acid, written as HF; nitrogen dioxide, written as NO2; and phosphorus pentoxide, written as P2O5. A binary molecular compound is a compound composed of two non-metal elements.

Full Answer

Other examples of binary molecular compounds include nitrogen trifluoride, dihydrogen monosulfide and sulfur hexafluoride. The atoms in these compounds combine using covalent bonds, whereas compounds with salts contain ionic bonds. Binary molecular compounds are named by giving the second element the suffix "-ide." Numerical prefixes for each element indicate the number of atoms present. For example, P406 uses the prefixes "tetra-" and "hex-" to indicate four atoms of potassium and six atoms of oxygen in tetraphosphorus hexoxide.

  • Q:

    How do aqueous solutions of ionic and molecular compounds differ?

    A:

    Aqueous solutions of ionic compounds are good conductors of electricity while solutions of molecular compounds are not. This is true because the individual ions in ionic compounds may completely dissociate in water with molecules remaining whole. Ionic and molecular compounds also affect the boiling and melting points of water.

    What is "seesaw" molecular geometry?

    A:

    The seesaw configuration in molecular geometry is a variation of the trigonal bipyramid configuration. The seesaw configuration occurs when there is a lone electron pair and four atoms are attached to the central atom. Sulfur tetrafluoride is an example of a trigonal bipyramid configuration exhibiting a seesaw structure.
