A hydrocarbon X undergoes the reaction under suitable conditions as shown below.

Question

K, L and M are beakers containing three different solutions: [Beaker K: Aqueous acetic acid, Beaker L: Sodium chloride solution, Beaker M: Distilled water]. Name the beaker which:
(a) contains only ions.
(b) contains only molecules.
(c) has pH less than 7.

Answer 1

The given reaction involves a hydrocarbon X undergoing a reaction to form products Y and Z. The question asks us to identify which of the compounds (X, Y, Z or combinations) the reaction describes. Let's analyze the reaction step-by-step.

X is a saturated hydrocarbon (alkane) with a single bond structure as shown in the left part of the image. This indicates a typical composition like C_nH_2n+2.
Y and Z are unsaturated hydrocarbons (alkenes) with double bonds, as seen in their structures. This suggests a possible dehydrogenation or cracking process, which converts an alkane to alkenes.
The reaction given is consistent with cracking, a process where alkanes like X are broken down into smaller alkenes like Y and Z under high temperature or catalytic conditions.
Since option Y is the only product that aligns with this transformation, it is justified to pick "Y only" as the correct answer.

Therefore, the correct answer is that the reaction describes the formation of Y only.
