Water is a desirable reaction medium chiefly because it is

  • A.cheap, non-toxic and non-flammable
  • B.a good solvent for every organic compound
  • C.easily evaporated with little energy
  • D.chemically inert toward all reagents

Answer: A

Correct answer: cheap, non-toxic and non-flammable

Water scores on every count that makes a solvent troublesome: it costs almost nothing, poses no toxic or fire hazard, and needs no special handling or disposal. Its drawbacks are that many organic compounds will not dissolve in it and that removing it is expensive, since its latent heat of vaporisation is high.
