There are 5 areas of chemistry:physical chemistry, organic chemistry, analytical chemistry, biochemistry and inorganic chemistry. identify which of the five area of chemistry best fits the action done by Sam, a chemist. Sam is studying the reactions of a class of compounds called ethers. The formula of one type of ether is CH3OCH3 If someone could help me I would really appreciate it. Thank you!
