Correct Option: B

While H2 is not very reactive under standard conditions, it does form compounds with most elements. Millions of hydrocarbons are known, but they are not formed by the direct reaction of elementary hydrogen and carbon. Hydrogen can form compounds with elements that are more electronegative, such as halogens. Hydrogen forms a vast array of compounds with carbon. Tetraphenylethylene is a chemical compound that can be used in construction and n the manufacture of medical equipment, packaging, and electrical appliances. Tetraphenylethylene can be synthesized from diphenyldichloromethane.
