Question

Hydracids contain ________ atom.
A) Hydrogen
B) Oxygen
C) Both A) and B)
D) None of the above

Answer 1

Hint: The answer to this question is based on the fact about the hydracids which means they are the binary compounds of hydrogen and a halogen or also pseudo halogens. This fact gives you the correct answer.

Complete Solution :
In the lower classes of chemistry, we have dealt with the terms like oxyacids, hydracids, oxo compounds and many other terminologies which give the meaning by its name itself.
We shall now see what hydracids are and also their usefulness.
Hydracids are basically the binary compounds that consist of hydrogen and halides or can also be the pseudo halides.
- These hydracids are also called binary acids where the hydrogen combines with the second non metallic element.
- The strength of the hydracids depend on the solvation of the initial acid, also the bond energy of the H - X bond, the electron affinity of the halides ‘X’ or also the pseudo halides and finally the salvation energy of the halides.
- The names of the binary acids usually begin with hydro – which is followed by the name of the other atom which later ends with – ic.
- Binary acids are one of the classes of acids that are two classes of acids, hydracids and oxyacids.
- Oxyacids are also called ternary acids which contain oxygen along with hydrogen and at least one other element.
Based on these facts, we can say that hydracids contain only hydrogen atoms.
So, the correct answer is “Option A”.

Note: Note that pseudo halogens are those compounds that are the polyatomic analogues of halogens whose chemistry resembles the true halogens and which allows them to substitute for halogens in several compounds. Examples can be cited as cyanogen ${{(CN)}_{2}}$.
