(a) What are the ways in which chemistry has changed the medical field?

(b) Give one or more examples of how chemistry has affected another science.

For part A, let's outline two important contributions of chemistry to the medical field:

• Organic chemistry has allowed scientists to modify molecules to create new medicines.
• Chemistry helped discover the concept of chirality (and enantiomers), which had effects on the production of medicines. For example, one enantiomer of Thalidomide caused birth defects. This example led developers to become aware of when a substance is chiral and thus study the effects of both enantiomers (or to engineer a resolution process to separate the desired enantiomer) before distribution.

For part B:

• Chemistry has impacted material design by creating new materials like plastics.
• Chemistry has impacted the design of different types of solar panels by utilizing dyes or doping silicon with impurities to create n-type and p-type layers.
