6) What is the inorganic compound that can be considered the structural basis for alcohols and ethers? Discuss two ways in which the physical properties of alcohols and ethers are similar to properties of this compound.
Answer: Alcohols and ethers can be considered to be derivatives of
water. Similar physical properties include:
Polarity: Water is a
very polar molecule; alcohols and ethers also display
polarity.
Boiling point: Water has a higher boiling point than
predicted on the basis of its molar mass. Alcohols also share this
characteristic, but ethers do not.
Solubility: Water is miscible
with other polar liquids; alcohols and ethers of low molar mass are
miscible with water and with each other because of their polarity.

69) Oxidation reactions are defined differently in organic chemistry than they are in inorganic chemistry. Give the definition of both and explain their similarities.
Answer: The inorganic definition of oxidation is loss of electrons. The organic definition is formation of additional bonds between carbon and oxygen (or a decrease in the number of carbon-hydrogen bonds). These are similar because when carbon forms a bond with electronegative oxygen, it essentially loses some of its attraction for its electrons.
