Choose the incorrect statements from the following:

(A) The dipole moment of cyclohexyl chloride is smaller than chlorobenzene.
(B) Alkyl halides are immiscible with water.
(C) The dipole moment of methyl chloride is higher than that of methyl fluoride.
(D) Chloroform renders aerial oxidation in the presence of oxygen

Choose the correct answer from the options given below:

(A), (B) and (D) only

The correct answer is Option 1 - (A), (B) and (D) only

(A)The dipole moment of cyclohexyl chloride is smaller than chlorobenzene. - Incorrect because in chlorobenzene, resonance between the benzene ring and the chlorine atom reduces the polarity of the C–Cl bond, lowering its dipole moment. In cyclohexyl chloride, such resonance is absent and the C–Cl bond remains more polar, giving it a higher dipole moment than chlorobenzene.

(B) Alkyl halides are immiscible with water.  Incorrect (as a general statement)
Lower alkyl halides (like CH₃Cl, C₂H₅Cl) show slight solubility in water. So saying “immiscible” absolutely is not correct.

(C) The dipole moment of methyl chloride is higher than that of methyl fluoride.  Correct
Due to bond length and resultant dipole, CH₃Cl has a slightly higher dipole moment than CH₃F.

 (D) Chloroform renders aerial oxidation in the presence of oxygen - Incorrect because chloroform does not cause aerial oxidation; instead, it undergoes oxidation in the presence of oxygen and light to form phosgene (COCl₂), which is toxic.
