(a)
Interpretation :
The name of compound
Concept Introduction :
A compound is said to be acidic in nature if there is one or more ionizable hydrogen ions present in it. The hydrogen atom is ionization if it is attached to more electronegative atom (generally oxygen).
(a)
Answer to Problem 5RQ
Explanation of Solution
A substance that can accept an electron pair to form a covalent bond is also act as an acid. The given molecule has 2 H atoms, 1 S atom and 4 O atoms.
Two oxygen atoms are bonded to S atom via double bonds and two oxygen atoms via single bonds. The hydrogen atoms are attached to two oxygen atoms which are attached to S via single bonds. Thus, there are 2 ionizable hydrogen atoms and it is acidic in nature. The name of the compound is sulfuric acid.
(b)
Interpretation :
The name of compound HNO3 needs to be explained.
Concept Introduction :
A compound is said to be acidic in nature if there is one or more ionizable hydrogen ions present in it. The hydrogen atom is ionization if it is attached to more electronegative atom (generally oxygen).
(b)
Answer to Problem 5RQ
Explanation of Solution
The given compound is made by the reaction of nitrogen dioxide
(c)
Interpretation :
The name of compound HBr needs to be explained.
Concept Introduction :
A compound is said to be acidic in nature if there is one or more ionizable hydrogen ions present in it. The hydrogen atom is ionization if it is attached to more electronegative atom (generally oxygen).
(c)
Answer to Problem 5RQ
Explanation of Solution
The given compound is HBr. There is 1 H atom and 1 Br atom present in it. Due to higher electronegtaivity of Br than H, Br can pull the electron pair towards itself making H atom ionizable. Therefore, name of the compound is hydrobromic acid.
(d)
Interpretation :
The name of compound HClO4 needs to be explained.
Concept Introduction :
A compound is said to be acidic in nature if there is one or more ionizable hydrogen ions present in it. The hydrogen atom is ionization if it is attached to more electronegative atom (generally oxygen).
(d)
Answer to Problem 5RQ
Explanation of Solution
In the given compound, there is 1 H atom, 1 Cl atom and 4 O atoms. 3 O atoms are bonded to Cl via double bonds. One oxygen atom is bonded via single bond and has 1 H atom bonded to it. Thus, it is an acid and the name of the acid is perchloric acid.

- Which carbocation is more stable?arrow_forwardAre the products of the given reaction correct? Why or why not?arrow_forwardThe question below asks why the products shown are NOT the correct products. I asked this already, and the person explained why those are the correct products, as opposed to what we would think should be the correct products. That's the opposite of what the question was asking. Why are they not the correct products? A reaction mechanism for how we arrive at the correct products is requested ("using key intermediates"). In other words, why is HCl added to the terminal alkene rather than the internal alkene?arrow_forward

An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box..
