1.	Account for the following (a) Haloarenes are less reactive towards nucleophilic substitution reactions.(b) Grignard reagents should be prepared under anhydrous conditions .(c) Melting point of p- dichlorobenzene is more than O & m isomers.
Answer» (a) due to resonance a partial double bond character is developed between C & X or any other suitable reason (b) because they are highly reactive towards any source of H⁺ (c) due to more symmetry of p-dichlorobenzene.

In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. (i) Assertion and reason both are correct and reason is correct explanation of assertion. (ii) Assertion and reason both are wrong statements. (iii) Assertion is correct but reason is wrong statement. (iv) Assertion is wrong but reason is correct statement. (v) Assertion and reason both are correct statements but reason is not correct explanation of assertion.Assertion: In monohaloarenes, further electrophilic substitution occurs at ortho and para positions.Reason: Halogen atom is a ring deactivator.
