Statement A : Haloalkanes are very slightly soluble in water. Statement B : New intermolecular attraction between haloalkanes and solvent molecules have much more strength than intermolecular attraction between haloalkanes molecules.
1 Statement A is correct but statement B is incorrect.
2 Statement A is incorrect but statement B is correct.
3 Both statements are correct.
4 Both statements are incorrect.
Explanation:
Haloalkanes are slightly soluble in water. Less energy is released when attraction between haloalkanes and water molecules takes place. As a result solubility of haloalkane in water is low.

Which of the following statement(s) is false?
1 Lower alkyl halides are either colourless gases (or) volatile liquids.
2 Alkyl halides are very soluble in water.
3 Alkyl halides burns on Cu wire with green edged flame.
4 The higher alkyl halides are colourless solids.
Explanation:
Alkyl halides are partially soluble in water.

Assertion : p-Dichlorobenzene is less soluble in organic solvents than the corresponding o- isomer. Reason : o-Dichlorobenzene is polar while p-dichlorobenzene is not.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The greater symmetry of p-dichlorobenzene compared to the o-isomer results in a tighter fit within the crystal lattice, requiring more energy to disrupt the lattice structure. Consequently, the p-isomer is less soluble than the o-isomer. So option (2) is correct.

Which of the following statements is true in case of alkyl halides?
1 They are polar in nature
2 They can form hydrogen bonds
3 They are highly soluble in water
4 They undergo addition reactions
Explanation:
Alkyl halides are insoluble in water but soluble in organic solvent, polar in nature and undergo substitution or elimination reactions.
