Chemistry

In presence of light allylic substitution occur.

In presence of CCl₄, addition reaction will occur.

KMnO₄ decomposes upon heating at 513 K and forms K₂MnO₄ and MnO₂.

2KMnO₄  K₂MnO₄ + O₂ + MnO₂

Group number = 11 (Atomic number = 111)

Release of toxic/undesirable materials in the environment.

Coca alkaloid or cocaine is obtained from Erythroxylum coca.

Functional group should get the lowest possible number.

Krypton (Kr)  belongs to the zero group element as per Mendeleev's periodic table.

Please find the solution below:

The boiling point of alcohol increases with increase in the number of carbon atoms. So, hexanol has maximum boiling point.
