The text describes carbon as the 'virtuoso of the covalent bond' in living matter. Which of the following best explains why carbon is considered essential for the great diversity of organic molecules?

  • A: Carbon forms strong ionic bonds with various elements.
  • B: Carbon's ability to form stable bonds with four other atoms, including other carbons, allows for diverse skeletons and chemical groups.
  • C: Carbon is the most abundant element in living organisms.
  • D: Carbon primarily forms single bonds, leading to rigid molecular structures.

Explanation

The text states: 'The versatility of carbon makes possible the great diversity of organic molecules, each with particular properties that emerge from the unique arrangement of its mostly carbon skeleton and the chemical groups attached to that skeleton.' This is due to its ability to form four stable covalent bonds, including with other carbon atoms.
