Finely ground plant material can be treated with a base to aid in the extraction of alkaloids present in the tissue. Explain why.

Interpretation Introduction

Interpretation:

The reason as to why finely ground plant material can be treated with a base to aid in the extraction of alkaloids present in the tissue is to be explained.

Concept introduction:

An organic compound consists of carbon and hydrogen. They can be classified as natural or synthetic compounds. Organic compounds also consist of heteroatoms like sulphur, oxygen, and nitrogen. Alkaloids are nitrogen containing compounds.

Explanation of Solution

Alkaloids are basic in nature due to which the reaction of alkaloids with base is not possible. They are nitrogen containing compounds. The other compounds like acid are also present in the plant...
