Butyric acid has a putrid odor. Suppose you got some on your hands and water did not wash it off. What might you do to remove the acid? (Hint: how could you make it more soluable in water)
What are the resonance structures for [H2CNO2]-? The problem asks for the major and minor contributors. The answer key says that there are two structures in which the only double bond switches between the two NO bonds
Benzene (C6H6) is converted to cyclohexane (C6H12) by direct addition of hydrogen gas H2. The plant produces 100 Ib-moles/hr of cyclohexane. 90% of benzene fed to the process reacts to form cyclohexane.
