Evaluate each of the following as an acceptable name for water: a. dihydrogen oxide b. hydroxide hydride c. hydrogen hydroxide d. oxygen dihydride

Water is a molecule consisting of two hydrogen atoms bonded to one oxygen atom. The chemical formula of water is H2O.

Now, let's evaluate each given name for the water molecule and check if it correctly represents the chemical composition and bonding in H2O. a. dihydrogen oxide The name "dihydrogen oxide" indicates that there are two hydrogen atoms (dihydrogen) and one oxygen atom (oxide) in the molecule. This name correctly represents the chemical formula (H2O) and is an acceptable name for water. b. hydroxide hydride "Hydroxide" (OH-) is a polyatomic ion that represents one hydrogen and one oxygen atom, and "hydride" (H-) is an ion that refers to a hydrogen atom. This name suggests a bonding between these ions (OH- and H-), but it doesn't accurately represent the bonding in a water molecule. Thus, "hydroxide hydride" is not an acceptable name for water. c. hydrogen hydroxide "Hydrogen hydroxide" indicates one hydrogen atom (hydrogen) and a hydroxide group (OH-) in the molecule. This name suggests that there might be two hydrogen and one oxygen atom in the molecule, similar to the chemical formula H2O. Although not a standard way to name water, hydrogen hydroxide can be considered an acceptable name. d. oxygen dihydride "Oxygen dihydride" indicates one oxygen atom (oxygen) and two hydrogen atoms (dihydride) in the molecule. This name correctly represents the chemical formula (H2O) and thus can be considered an acceptable name for water. In summary, the acceptable names for water among the given options are: a. dihydrogen oxide c. hydrogen hydroxide d. oxygen dihydride
