In the above given reaction, alkaline KMnO4 acts as
विकल्प
reducing agent
oxidising agent
catalyst
dehydrating agent

उत्तर
oxidising agent
Explanation -
In this reaction, alkaline potassium permanganate is adding oxygen to ethanol and hence, oxidising it to acetic acid. Substances that are capable of adding oxygen to others are known as oxidising agents.

Give an example for each of the following statement
A compound in which two Covalent bonds are formed.
Identify the incorrect statement and correct them.
- Like covalent compounds, coordinate compounds also contain charged particles (ions). So they are good conductors of electricity.
- Ionic bond is a weak bond when compared to Hydrogen bond.
- Ionic or electrovalent bonds are formed by mutual sharing of electrons between atoms.
- Loss of electrons is called Oxidation and gain of electron is called Reduction.
- The electrons which are not involved in bonding are called valence electrons.
