Chemistry Safety Quiz
The green chemistry goal of designing chemicals with "little or no toxicity" is a challenge
because
(a) All chemicals are toxic at a high enough dose
(b) TCSA does not require chemical companies to assess toxicity, therefore we know little
about the toxicity of many chemicals
(c) The "least toxic" chemicals are already being used and produced by chemical
manufacturers
(d) Both (a) and (b)
d) both a and b
What are the green features of a chemical synthesis?
(a) High yield, approaching 100%
(b) Use of less-toxic reagents
(c) Production of less-toxic by-products
(d) All of the above
d) All of the above
Using catalysts in reactions is a green step because
(a) Catalysts are inherently nontoxic
(b) Catalysts are generally used in safer solvents
(c) Catalysts allow reactions to be run under less energy intensive conditions
(d) Most catalysts are biological in nature and therefore less toxic
c) Catalysts allow reactions to be run under less energy intensive conditions
Which solvent is the greenest?
(a) Hydrocarbon with halogens
(b) Perhalogenated hydrocarbon
(c) Supercritical carbon dioxide
(d) Solvent with very high boiling point
c) Supercritical carbon dioxide
Sustainability means meeting the needs of the present
(a) And ensuring a high standard of living for U.S. citizens
(b) And allowing the future generation to take care of themselves
(c) Without compromising the ability of future generations to meet their own needs
Without interference from government regulations and laws
c) Without compromising the ability of future generations to meet their own needs
