Carbon can form all of the following except:

  1. a. Double bonds

  2. b. Triple bonds

  3. c. Ionic bonds

  4. d. Quadruple bonds

The correct answer is: d. Quadruple bonds

Carbon is a versatile element that can form multiple types of chemical bonds. It is capable of forming single, double, and triple bonds with other atoms. However, it cannot form quadruple bonds. This is because the maximum number of bonds an atom can form is four, and carbon already has four valence electrons for bonding. Therefore, options A, B, and C are incorrect, as carbon can form all of them. Option D is incorrect because it implies that carbon can form more than four bonds, which is not possible.
