Question

Write the structure which has lowest molecular mass hydrocarbon[non- =cyclic] as per 1*,2*,3* and 4* sequentially

Answer 1

Explanation:

The largest database[1] of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. The number of potential organic compounds has been estimated[2] at 1060—an astronomically high number. The existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities.
