Concept explainers
(a)
Interpretation: The vitamins which contain sulfur have to be predicted.
Concept introduction: The organic compounds which are essential in small amounts for the proper functioning of the human body are called vitamins. The vitamins should be taken through diet. There are two types of vitamins, fat-soluble vitamins and fat-soluble vitamins.
(b)
Interpretation: ion: The vitamin which doesn’t have a cyclic component has to be predicted.
Concept introduction: The organic compounds which are essential in small amounts for the proper functioning of the human body are called vitamins. The vitamins should be taken through diet. There are two types of vitamins, fat-soluble vitamins and fat-soluble vitamins.
(c)
Interpretation: ion: The vitamin which contains one or more alcohol functional group has to be predicted.
Concept introduction: The organic compounds which are essential in small amounts for the proper functioning of the human body are called vitamins. The vitamins should be taken through diet. There are two types of vitamins, fat-soluble vitamins and fat-soluble vitamins.
(d)
Interpretation: The vitamins which contain both fused and non fused ring systems have to be predicted.
