An organic compound ‘A' gives orange ppt with 2,4 DNP to produce ‘B'. ...
Identification of Organic Compounds A, B, and C
Organic compound A is identified as a carbonyl compound, such as an aldehyde or ketone, due to the formation of an orange precipitate with 2,4-dinitrophenylhydrazine (2,4-DNP) to produce compound B.

Chemical Equation for the Reaction of A with 2,4-DNP:
A + 2,4-DNP → B (orange ppt)
Compound A further reacts with iodine (I₂) and sodium hydroxide (NaOH) to form a yellow precipitate C, indicating the presence of a methyl ketone group.

Chemical Equation for the Reaction of A with I₂ and NaOH:
A + I₂ + NaOH → C (yellow ppt)
Given that the molar mass of compound A is 72, it could possibly be acetone (CH₃COCH₃) with a molar mass of 72 g/mol.

Identification of A, B, and C:
- Compound A: Acetone (CH₃COCH₃)
- Compound B: 2,4-DNP derivative of acetone
- Compound C: Iodoform (CHI₃)
Therefore, the organic compounds A, B, and C are identified as acetone, 2,4-DNP derivative of acetone, and iodoform, respectively.

Read the information given below carefully and answer the following question.The whole biosphere, like the individual organisms that live inside it, exists in a chemically dynamic state. In this homeostatic system, a great number of organic compounds are synthesized, transformed, and decomposed continuously; together, these processes constitute the major parts of the carbon cycle. For the smooth operation of this cycle, degradation is just as important as synthesis: the green plants produce great quantities of polymers, such as cellulose, and innumerable other compounds like alkaloids, terpenes, and flavonoids, that green plants cannot use as sources of energy during respiration. The release of the carbon in these compounds forrecycling depends almost entirely on the action of both aerobic and anaerobic bacteria and certain types of fungi. Some bacteria and fungi possess the unique and extremely important biochemical asset of being able to catalyse the oxidation of numerous inert products, thereby initiating reaction sequences that produce carbon dioxide and so return much carbon to a form that actively enters into life cycles once again.Q.The passage contains information that would answer which of the following questions about the carbon cycle?1. What are some of the compounds that are broken down in the carbon cycle?2. Why are some compounds that are involved in the carbon cycle less reactive than others? 3. What role do bacteria and fungi play in the carbon cycle?
