Approach Solution -2
Sulfuric acid \((H_2SO_4)\) is a strong acid composed of hydrogen, sulfur, and oxygen. The anhydride of an acid is the compound formed by removing water \((H_2O)\) from the acid.
To determine the anhydride of sulfuric acid, we can follow this general reaction for forming an anhydride from an acid:
\(Acid−Water=Anhydride\)
For sulfuric acid \((H_2SO_4\)
\(H_2O)\) from sulfuric acid results in sulfur trioxide \((SO_3)\)
Thus, \((SO_3)\) is the anhydride of sulfuric acid.

Top Questions on Group 16 Elements
- Given below are two statements :
Statement I: The boiling point of hydrides of Group 16 elements follow the order
H2O > H2Te > H2Se > H2S.
Statement II: On the basis of molecular mass, H2O is expected to have lower boiling point than the other members of the group but due to the presence of extensive H-bonding in H2O, it has higher boiling point.
In the light of the above statements, choose the correct answer from the options given below :- NEET (UG) - 2024

Concepts Used:
Group 16 Elements
The group 16 elements (oxygen group elements) of the periodic classification are also known as chalcogens because most of the copper ores have copper in the form of oxides and sulphides. The word chalcogen means “ore formation” which is derived from the Greek word “Chalcos” (Ore) and “gen” (formation).
There are 5 elements that come under Group 16 of the Modern Periodic Table namely:
- Oxygen (O)
- Sulphur (S)
- Selenium (Se)
- Tellurium (Te)
- Polonium (PO)
Electronic Configuration:
The general electronic configuration of the chalcogens can be written as ‘ns2np4’, where ‘n’ denotes the value of the principal quantum number corresponding to the valence shell of the element.
The electron configuration of the synthetic element livermorium (believed to be a chalcogen) is predicted to be [Rn]5f146d107s27p4.
Metallic Nature of the Group 16 Elements:
- Oxygen and sulfur are classified as non-metals.
- Selenium and tellurium are classified as metalloids.
- Under standard conditions, polonium exhibits metallic characteristics. However, it is important to note that polonium is a radioactive element.
