<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
Answer: The IUPAC name of is 5-chloro-2-pentyne
Explanation:
1. First select the longest possible carbon chain. For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
2. The longest possible carbon chain should contain all the bonds and functional groups.
3. The numbering is done in such a way that the carbon containing the functional group or substituent gets the lowest number. Triple bond is given priority over substituent halogen.
4. The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne.
Thus the IUPAC name of is 5-chloro-2-pentyne
