Question

In an experiment to study the properties of acetic acid, a student takes about $2ml$ of acetic acid in a dry test tube. He adds about $2ml$ of water to it and shakes the test tube well. He is likely to observe that:
A.The acetic acid dissolves readily in water.
B.The solution becomes light orange
C.Water floats over the surface of acetic acid
D.Acetic acid floats over the surface of water.

Answer 1

The derivatives of carbon are known as organic compounds. Acetic acid is also an organic compound and it is also known as ethanoic acid. Acetic acid is capable of forming hydrogen bonds due to the presence of oxygen and hydrogen atoms in it.

Complete step by step answer:
The compounds containing carbon and the derivatives of carbon are known as organic compounds. The compounds related to carbon elements are considered as organic compounds because all the living beings, plants, animals and rocks consist of carbon. The carbon is the basic element which is used to determine the age of fossils using the radioactivity mechanism.
Acetic acid is also an organic compound composed of carbon, oxygen and hydrogen atoms. The chemical formula of acetic acid is $C{H_3}COOH$. Acetic acid is also known as ethanoic acid and vinegar is one of the productions from the acetic acid. When naturally occurring carbohydrates are fermented and oxidized they produce a dilute carboxylic acid solution, this dilute carboxylic acid solution is known as vinegar.
When acetic acid is dissolved in water it forms hydrogen bonds with water molecules. As we all know that acetic acid has a carboxyl group which has two oxygen atoms and a hydrogen atom and the water molecules also have hydrogen and oxygen atoms so the hydrogen bonding takes place efficiently and the acetic acid is completely dissolved in the water.
So when a student mixes the acetic acid and the water, and shakes the test tube well the acetic acid dissolves readily in the water.
So option (A) is correct.

Note: Hydrogen bonding is nothing but a dipole – dipole attraction between the atoms of molecules. The hydrogen bonding basically occurs between the covalently bonded highly electronegative element and the other electronegative elements. The elements responsible for hydrogen bonding are nitrogen, oxygen and fluorine.
