Question

Why is carbon preferable to be the chemical base for life?

a. Carbon dioxide is essentially insoluble in water.

b. Carbon dioxide is a strong construction material.

c. The stability and strength of the carbon–carbon bonds make it a good base

for larger molecular complexes.

d. It escapes the biochemical circulation once it is utilized.

e. By reacting with hydrogen, it can undergo combustion, which provides

organisms with energy.

Answer 1

Answer: c. The stability and strength of the carbon–carbon bonds make it a good base for larger molecular complexes.

Carbon can form bond with four other atoms.

The bond energy of c-c bond is so high that it is suitable to form large complex molecules with long chains, because of these molecules, life is existing

These complex molecules are both stable and reactive

What we normally think of as 'life' is based on chains of carbon atoms, with a few other atoms, such as nitrogen or phosphorus", as per Stephen Hawking in one of his lectures in 2008
