<u>Answer:</u> The mass of carbon in given amount of carvone is 47.52 grams
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
Given mass of carvone = 55.4 g
Molar mass of carvone = 150.22 g/mol
Putting values in equation 1, we get:
The chemical formula of carvone is
This contains 10 moles of carbon atom, 14 moles of hydrogen atom and 1 mole of oxygen atom
Now, calculating the mass of carbon in carvone from equation 1, we get:
Molar mass of carbon = 12 g/mol
Moles of carbon = (10 × 0.396) = 3.96 moles
Putting values in equation 1, we get:
Hence, the mass of carbon in given amount of carvone is 47.52 grams
Below Mechanism shows the mechanism of formation of diazonium ion. Aniline is treated with Nitrosonium ion which is generated in situ by the reaction of Sodium nitrile and strong acid. The resulting <span>benzenediazonium ion on reaction with CuBr yields Bromobenzene and on treatment with CuCN gives Benzonitrile. Mechanism is as folow,</span>
