The following two puzzles don’t require much knowledge of chemistry. They are basically LOGIC puzzles.

Among the six molecules below, there are two that are classified as alcohols, two ketones, one aldehyde and one carboxylic acid.

C₃H₆O, C₂H₄O₂, CH₄O, C₃H₈O, C₂H₄O, C₄H₈O

Use the following statements to figure out which formulas correspond to which groups( alcohol, ketone, aldehyde or carboxylic acid). Careful: one of the statements below is FALSE!

1. Neither CH₄O nor C₄H₈O, which is not an alcohol, is an aldehyde; C₃H₆O isn’t either.
2. The carboxylic acid is not C₃H₆O or C₃H₈O.
3. The aldehyde is not C₂H₄O₂ or C₃H₈O.
4. C₂H₄O is neither a ketone nor an alcohol.
5. The acidic molecule is neither CH₄O nor C₄H₈O, which is not an alcohol.
6. C₂H₄O is neither an aldehyde nor a carboxylic acid.
7. C₃H₆O is not one of the alcohols.

Four particles (kaon ,muon, photon, and neutron) belong to four different categories: (baryon, gauge, lepton and meson). Each has a different rest mass (0, 106, 494, and 940). From the statements below, fill out the following table:

1. The particle whose rest mass is 106 is not a meson or a baryon.
2. The gauge particle has the lowest rest mass.
3. A kaon is neither a gauge nor a baryon, and its rest mass is not 106.
4. A photon is not a baryon.
5. A neutron’s rest mass is not 494. And neither the neutron nor the photon has a rest mass of 106.
