STEM Organic Distinction Problem 28: How can you chemically distinguish between phenol (C6H5OH) and ethanol (C2H5OH) using a simple qualitative test?
Adding sodium metal: only ethanol reacts with sodium
Adding neutral FeCl3 solution: phenol produces a distinct violet color, whereas ethanol shows no change
Heating with concentrated sulfuric acid at 180°C
Adding litmus paper: ethanol turns blue litmus red

STEM Transition Elements Problem 44: Why are most compounds of transition metals in the first series colored and paramagnetic?
Because of the total absence of electrons in the d-subshell
Because they possess completely filled 3d10 orbitals
Due to the presence of unpaired electrons in 3d orbitals that absorb specific wavelengths of visible light for d-d excitation
Due to nuclear fission within the metal atom
