What is the IUPAC name of the following compound?
1 answer:
Answer:
(d) 3,7-dimethyl-4-nonyne.
Explanation:
Hello,
In this case, considering the attached picture on which you can see that the main chain has nine carbon atoms, one tripe bond at the fourth carbon and two methyl radicals at the third and seventh carbons respectively, by following the IUPAC rules, the name would be: (d) 3,7-dimethyl-4-nonyne since the chain must start at the side closest to the first triple bond due to its priority and subsequently considering the present radicals.
Best regards.

Explanation:
Hello!
In this case, given the initial conditions, we first use the 10-% quality to compute the initial entropy:
Now the entropy at the final state given the new 40-% quality:
Next step is to compute the mass of steam given the specific volume of steam at 175 kPa and the 10% quality:
Then, we can write the entropy balance:
Whereas sfg stands for the entropy of the leaving steam to hold the pressure at 150 kPa and must be greater than 0; thus we plug in:
Which is such minimum entropy change of the heat-supplying source.
Best regards!
