Identify the correct order for the given property for following compounds. (A) Boiling Point : ethyl chloride < ethyl bromide < ethyl iodide (B) Density : ethyl bromide < ethyl chloride < ethyl iodide (C) Boiling Point : ethyl bromide < isopropyl bromide < tert-butyl bromide (D) Density : sec-butyl iodide > 1-bromobutane > 1-chlorobutane (E) Boiling Point : ethyl chloride > isobutyl chloride > tert-butyl chloride Choose the correct answer from the option given below : (1) (A), (C) and (E) only (2) (A), (B) and (E) only (3) (A), (C) and (D) only (4) (B), (C) and (D) only

1. (A), (C) and (E) only
2. (A), (B) and (E) only
3. (A), (C) and (D) only
4. (B), (C) and (D) only

Correct answer: (A), (B) and (E) only

Solution

The correct option is right because it accurately reflects the trends in boiling points and densities of the compounds based on their molecular weights and intermolecular forces. Ethyl chloride, ethyl bromide, and ethyl iodide show increasing boiling points due to larger molecular sizes and stronger van der Waals forces, while the density trends align with the increasing molecular weights of the halogenated compounds.
