The answer is STRAIGHT, I think!
Answer:
The correct name is 5-chloro-2-pentyne.
Explanation:
- <em>Kindly see the attached image.</em>
- It summarizes the rules of IUPAC system to name the compounds.
- We have 5 carbon atoms that take the name (pent).
- The carbon skeleton should be numbered that the position of the triple bond should have the lowest number in the skeleton, so the triple bond is between C2 and C3.
- It takes the lowest number (2) and added (yne) at the end of the name.
- (yne) is express the presence of triple bond.
- The (Cl) atom take the number 5.
- <em>So, the correct name of the compound is 5-chloro-2-pentyne.</em>
The four metals that will not replace hydrogen in an acid are Cu, Ag, Au, Hg.
Explanation:
- As Copper Cu lies below the hydrogen, this is why it is less reactive and ca not replace Hydrogen from its compound.
- Silver Ag also lies below the hydrogen and therefore it is less reactive to displace Hydrogen.
- Gold Au becomes less reactive than Hydrogen due to its placement below Hydrogen acid.
- Mercury Hg is less reactive than Hydrogen
