Secondary metabolites are toxic chemicals in plants that are not used in or derived from photosynthesis or respiration. What are

Anuta_ua [19.1K]

Explanation:

Metabolites are the different kinds of the substances which are essential to metabolism of the organism.

Metabolites produced by the plants can be categorized into the primary metabolites and the secondary metabolites.

The primary metabolites have important role in survival of plant and play an active role in the respiration and the photosynthesis.

On the other hand, the secondary metabolites are not involved in normal growth and the development of plant. Although absence of these type of metabolites can lead to impairment of survivability of plant in long run.

<u>Secondary metabolites are produced mostly by the plants for the defense purposes.</u> They include steroids, alkaloids, phenolics, essential oils, resins, tannins, lignins, flavonoids, etc.

Which element is most likely to replace hydrogen in a displacement reaction?

LUCKY_DIMON [66]

Answer: The correct option is (D) lithium (Li).

Explanation: Hydrogen is the element which belong to period 1. The atomic number of hydrogen is, 1

The electronic configuration of hydrogen is,

The number of valence electrons present in hydrogen is, 1.

(A) Helium is the element which belong to period 1. The atomic number of helium is, 2

The electronic configuration of helium is,

The number of valence electrons present in helium is, 2.

(B) Oxygen is the element which belong to period 2. The atomic number of oxygen is, 8

The electronic configuration of oxygen is,

The number of valence electrons present in oxygen is, 6.

(C) Nitrogen is the element which belong to period 2. The atomic number of nitrogen is, 7

The electronic configuration of nitrogen is,

The number of valence electrons present in nitrogen is, 5.

(D) Lithium is the element which belong to period 2. The atomic number of lithium is, 3

The electronic configuration of lithium is,

The number of valence electrons present in lithium is, 1.

From this we conclude that the lithium element has the same number of valence electrons as hydrogen.

Hence, the correct option is (D) lithium (Li).
