Read the passage given below and answer the following questions:
Aryl halides are extremely less reactive towards nucleophilic substitution reactions due to the following reasons:
(i) In haloarenes, the electron pairs on halogen atom are in conjugation with π-electrons of the ring.
(ii) In haloalkane, the carbon atom attached to halogen is sp3 hybridised while in case of haloarene, the carbon atom attached to halogen is sp2 -hybridised.
(iii) In case of haloarenes, the phenyl cation formed as a result of self-ionisation will not be stabilised by resonance.
Q. A primary alkyl halide would prefer to undergo ________.

The π-electrons of the aromatic ring. This conjugation delocalizes the electron density over the entire ring system, making it less available for attack by nucleophiles.
(ii) The carbon-halogen bond in aryl halides is stronger and shorter compared to alkyl halides. This makes it more difficult for nucleophiles to break the carbon-halogen bond and replace the halogen atom.
(iii) The bulky nature of the aryl group also hinders the approach of nucleophiles towards the carbon atom.
(iv) In addition, the aromatic ring provides stability to the molecule through resonance, and any substitution reaction that breaks the aromaticity would be unfavorable.
Based on the information provided, we can answer the following questions:
1. Why are aryl halides less reactive towards nucleophilic substitution reactions?
- Aryl halides are less reactive towards nucleophilic substitution reactions due to the conjugation of electron pairs on the halogen atom with the π-electrons of the aromatic ring, which delocalizes the electron density and makes it less available for attack by nucleophiles. The stronger and shorter carbon-halogen bond, the bulky nature of the aryl group, and the stability provided by the aromatic ring also contribute to the lower reactivity.
2. How does conjugation affect the reactivity of aryl halides?
- Conjugation in aryl halides delocalizes the electron density over the entire aromatic ring system, making it less available for attack by nucleophiles. This reduces the reactivity of aryl halides towards nucleophilic substitution reactions.
3. What makes the carbon-halogen bond in aryl halides stronger and shorter compared to alkyl halides?
- The carbon-halogen bond in aryl halides is stronger and shorter compared to alkyl halides due to the presence of the π-electron cloud of the aromatic ring. This electron density is attracted towards the carbon-halogen bond, making it stronger and shorter.
4. How does the bulky nature of the aryl group affect the reactivity of aryl halides?
- The bulky nature of the aryl group hinders the approach of nucleophiles towards the carbon atom, reducing the reactivity of aryl halides towards nucleophilic substitution reactions.
5. Why would any substitution reaction that breaks the aromaticity be unfavorable?
- The aromatic ring provides stability to the molecule through resonance. Breaking the aromaticity would disrupt this stability, making any substitution reaction that breaks the aromaticity unfavorable.
(ii) The carbon-halogen bond in aryl halides is stronger and shorter compared to alkyl halides. This makes it more difficult for nucleophiles to break the carbon-halogen bond and replace the halogen atom.
(iii) The bulky nature of the aryl group also hinders the approach of nucleophiles towards the carbon atom.
