Chemistry - CHEMICAL BONDING Question with Solution | TestHub
Acids that contain hydrogen attached to oxygen along with another element (often a non metal) are termed as oxyacids. The basicity of oxyacids is determined by how many hydrogens are attached to oxygen atoms. They also show hydrogen bonding. Consider the following oxyacids.
(a) Pyrosulphurous acid
(b) Tetra polyphosphoric acid
(c) Peroxydisulphuric acid
(d) Isohypophosphoric acid
(e) Selenic acid
(f) Telluric acid
(g) Pyrosilicic acid
Number of acids that are dibasic and also contain linkage.
Answer:
Solution:
(a) Pyrosulfurous acid (): This acid is dibasic and contains a direct S-S linkage (structure: ).
(c) Peroxydisulfuric acid (): This acid is dibasic and contains an S-O-O-S linkage; it is typically grouped here as it involves a bridge between two central atoms.
Other Acids: (b) Tetrapolyphosphoric, (f) Telluric, and (g) Pyrosilicic are hexabasic; (d) Isohypophosphoric is tetrabasic; and (e) Selenic is mononuclear with no X-X linkage.
The acids that satisfy the criteria are (a) and (c).
Total Number = 2
