Answer: Option (3) is the correct answer.
Explanation:
When a linear chain of carbon and hydrogen atoms is attached by single bonds only then it is known as alkane.
When a linear chain of carbon and hydrogen atoms contains a double bond then it is known as alkene.
When a linear chain of carbon and hydrogen atoms contains a triple bond then it is known as alkyne.
Therefore, in the given description there is a double bond between third and fourth carbon. Hence, the IUPAC name of given compound is 3-heptene.
Answer:
2.88L
Explanation:
So lets first consider the definition of molarity.
Molarity is the amount of moles per one L of solution. So we can simply put this as:
M = moles/L of solution
So the way we are going to approach this is we need to find the amount of moles of HCl. By doing this we can then use the amount of moles we have to figure out how much 5M solution we can then make. So lets plug in what we know:
It gives us 12M of HCl so M = 12
We also have 1.2L of HCl so volume of soltion = 1.2L
Meaning we have:
So if we multiply the 1.2 over we get:
Moles: 14.4
So we used 14.4 moles of HCl in our original 12M solution.
Now we can plug this value with our 5M in instead to get our amount of solution we could form:
This gives us
5(volume) = 14.4 moles
Meaning that
Volume = 14.4/5 or 2.88L
