The following two puzzles don’t require much knowledge of chemistry. They are basically LOGIC puzzles.
LOGIC Puzzle #1
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!
LOGIC Puzzle #2
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:
