Detailed Solution

Total Number of Carboxylic Acid Groups in Product 'P'

The original compound undergoes the following sequence:

i) Acidic hydrolysis (H₃O⁺)

ii) Ozonolysis (O₃)

iii) Oxidative work-up (H₂O₂).

Stepwise analysis:

Ozonolysis breaks all double bonds and converts the suitable positions to carboxylic acids.
Oxidative work-up ensures full oxidation of all candidate groups to carboxylic acids.
Loss of 2 moles of CO₂ means two carboxylic acid groups are removed in the process.

After full oxidation, the typical number of carboxylic acid groups formed is 6. Subtracting the two groups lost as CO₂, the total is 4 carboxylic acid groups.

Final Answer: The total number of carboxylic acid groups in product 'P' is 4.
