Which one of the following elements forms highest number of compounds?

Options

  1. AOxygen
  2. BHydrogen
  3. CChlorine
  4. DCarbon

Correct answer

D. Carbon

Step-by-step solution

Carbon is the element which forms the highest number of compounds especially organic compounds due to its catenation(long chain formation) ability. . Carbon, with 4 valence atoms and by virtue of being in the 1st row of the periodic table is most suited to form the highest number of compounds.
