Answer 1

The misleading name" organic" is a relic of the days when chemical compounds

were divided into two classes, inorganic and organic, depending upon

where they had come from. Inorganic compounds were those obtained from

minerals; organic compounds were those obtained from vegetable or animal

sources, that is, from material produced by living organisms. Indeed, until about

1850 many chemists believed that organic compounds must have their origin in

living organisms, and consequently could never be synthesized from inorganic

material.
