ortho and para directing groups have all of the following properties EXCEPT:
Correct answer: A. They are not electron-donating groups
- A. They are not electron-donating groups
- B. They increase reactivity of mono- substituted benzene ring
- C. They facilitate the availabilty of electrons at ortho and para positions
- D. Halogen-substituted benzene is more reactive than benzene
Explanation
Ortho para directing groups are electron donating and increase the reactivity of benzene ring hence, the statement given in option a:"They are not electron-donating groups" is not correct.

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.
