To determine the conjugate bases that can deprotonate water, we need to identify strong bases. Strong bases are substances that readily accept a proton (H+) from another molecule. In this case, we need to find conjugate bases that have a higher affinity for protons than water.

Here are some examples of common conjugate bases that can deprotonate water:

  1. Hydroxide ion (OH-): Hydroxide ion is a strong base that can readily accept a proton from water, forming the hydroxide ion (OH-) and leaving behind a hydroxonium ion (H3O+).
    H2O + OH- → OH- + H3O+

  2. Amide ion (NH2-): Amide ion is another strong base that can deprotonate water to form hydroxide ion and an ammonium ion (NH4+).
    H2O + NH2- → OH- + NH4+

  3. Alkoxide ion (RO-): Alkoxide ion is a strong base derived from an alcohol. It can also deprotonate water to produce hydroxide ion and an alcohol.
    H2O + RO- → OH- + ROH

  4. Cyanide ion (CN-): Although toxic, cyanide ion is a strong base that can deprotonate water, leading to the formation of hydroxide ion and hydrogen cyanide (HCN).
    H2O + CN- → OH- + HCN

Note that the strength of a base is determined by its ability to accept a proton. The stronger the base, the more easily it can deprotonate water. These are just a few examples of conjugate bases that can deprotonate water. There are many other strong bases that can perform this reaction.
