The ortho and para-hydrogens possesses:
Correct answer: B. Different physical properties and same chemical properties
- A. Same physical properties and different chemical properties
- B. Different physical properties and same chemical properties
- C. Same physical and chemical properties
- D. Different physical and chemical properties
Explanation
The main difference between ortho and para-hydrogen is the spin of their nuclei. In ortho-hydrogen, the spins of the two nuclei are in the same direction, while in para-hydrogen, the spins of the two nuclei are in opposite directions. This difference in spin results in different physical properties, such as boiling point, specific heat, and thermal conductivity. However, ortho and para-hydrogen have the same chemical properties, meaning that they react in the same way with other substances.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
