A hydrocarbon ' $X$ ' with formula $C _6 H _8$ uses two moles of $H _2$ on catalytic hydrogenation of its one mole On ozonolysis, ' $X$ ' yields two moles of methane dicarbaldehyde The hydrocarbon ' $X$ ' is :
Show Hint
- hexa-1, 3, 5-triene
- 1-methylcyclopenta-1, 4-diene
- cyclohexa - 1, 3-diene
- cyclohexa-1, 4-diene
The Correct Option is D
Approach Solution - 1
so, the correct option is (D) : cyclohexa-1, 4-diene
Approach Solution -2
When the given hydrocarbon ‘X’ undergoes catalytic hydrogenation, two moles of \( H_2 \) are added, suggesting the presence of two double bonds.
Upon ozonolysis, two moles of methane dicarbaldehyde are produced, indicating that the molecule is a conjugated diene.
Thus, the structure of the hydrocarbon is cyclohexa-1, 4-diene.

Two cells of emf 1V and 2V and internal resistance 2 \( \Omega \) and 1 \( \Omega \), respectively, are connected in series with an external resistance of 6 \( \Omega \). The total current in the circuit is \( I_1 \). Now the same two cells in parallel configuration are connected to the same external resistance. In this case, the total current drawn is \( I_2 \). The value of \( \left( \frac{I_1}{I_2} \right) \) is \( \frac{x}{3} \). The value of x is 1cm.

Concepts Used:
Aldehydes, Ketones, and Carboxylic Acids
Aldehydes, Ketones, and Carboxylic Acids are carbonyl compounds that contain a carbon-oxygen double bond. These organic compounds are very important in the field of organic chemistry and also have many industrial applications.
Aldehydes:
Aldehydes are organic compounds that have the functional group -CHO.
Preparation of Aldehydes
Acid chlorides are reduced to aldehydes with hydrogen in the presence of palladium catalyst spread on barium sulfate.
Ketones:
Ketones are organic compounds that have the functional group C=O and the structure R-(C=O)-R’.
Preparation of Ketones
Acid chlorides on reaction with dialkyl cadmium produce ketones. Dialkyl cadmium themselves are prepared from Grignard reagents.
Carboxylic Acid:
Carboxylic acids are organic compounds that contain a (C=O)OH group attached to an R group (where R refers to the remaining part of the molecule).
Preparation of Carboxylic Acids
Primary alcohols are readily oxidized to carboxylic acids with common oxidizing agents such as potassium permanganate in neutral acidic or alkaline media or by potassium dichromate and chromium trioxide in acidic media.
