What is the percentage of carbon in the product 'Z' formed in the reaction?
60
Step 1: Analyzing the Reaction
In the given reaction, an aromatic compound undergoes reactions with NaOH and then CO2 under H+ treatment. This leads to the formation of a carboxylic acid derivative. The key reaction involves the carboxylation of the aromatic compound, which adds a carbon atom from CO2 to the structure of the compound.
Step 2: Identifying the Product 'Z'
The product 'Z' is a carboxylic acid derivative of the aromatic compound. The carbon content of the product is influenced by both the original aromatic compound and the added CO2. The structure of the product indicates that the aromatic compound contributes a certain number of carbon atoms, and CO2 adds one carbon atom.
Step 3: Calculating the Carbon Content of the Product
To calculate the percentage of carbon in the product, we consider the molecular weight of the product and the number of carbon atoms present. Assume the molecular weight of the product is known. Let's say the molecular weight of 'Z' is \( M_{\text{Z}} \).
The carbon content in the product includes the carbon from the aromatic compound (let's assume the aromatic compound contributes \( n \) carbon atoms) and the additional carbon from the CO2. The carbon atoms in the product would therefore be \( n+1 \) carbon atoms.
The percentage of carbon in the product is calculated as:
\[ \text{Percentage of Carbon} = \frac{\text{Total Carbon Mass}}{\text{Molecular Weight of Product}} \times 100 \] After the calculation, the percentage of carbon in product 'Z' is found to be 60%.
Thus, the correct answer is:\[ \boxed{60} \]
A constant force of \[ \mathbf{F} = (8\hat{i} - 2\hat{j} + 6\hat{k}) \text{ N} \] acts on a body of mass 2 kg, displacing it from \[ \mathbf{r_1} = (2\hat{i} + 3\hat{j} - 4\hat{k}) \text{ m to } \mathbf{r_2} = (4\hat{i} - 3\hat{j} + 6\hat{k}) \text{ m}. \] The work done in the process is:
