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. Reaction of C6H5CH2Br with aqueous sodium hydroxide follows _______.

The π-electrons of the aromatic ring. This conjugation delocalizes the electron density and makes it less available for attack by nucleophiles.
(ii) The carbon-halogen bond in haloarenes is shorter and stronger compared to the carbon-halogen bond in alkyl halides. This makes it more difficult for nucleophiles to break the bond and replace the halogen atom.
(iii) The aromatic ring in haloarenes is highly stable due to resonance and delocalization of electrons. This stability makes it less likely for the ring to undergo substitution reactions.
Questions:
1. Why are aryl halides less reactive towards nucleophilic substitution reactions?
2. What is the effect of conjugation on the reactivity of haloarenes?
3. How does the carbon-halogen bond length affect the reactivity of haloarenes?
4. What makes the aromatic ring in haloarenes highly stable?
