NEET Chemistry (general) MCQ Question
Which of the following statements are correct regarding the properties and reactivity of haloalkanes and haloarenes?
Haloalkanes have sp3 hybridized carbon atoms, while haloarenes have sp2 hybridized carbon atoms.
The C—Cl bond in haloalkanes is shorter than in haloarenes due to higher s-character in haloalkanes.
Haloarenes are generally more reactive than haloalkanes towards nucleophilic substitution reactions.
The C—Cl bond in haloarenes is shorter than in haloalkanes, making haloarenes less reactive.
Correct Answer
Detailed Explanation
Haloalkanes have carbon atoms that are sp3 hybridized, while haloarenes have sp2 hybridized carbon atoms, leading to differences in bond length and reactivity. The C—Cl bond in haloarenes is shorter and stronger than in haloalkanes, making haloarenes less reactive towards nucleophilic substitutions.
