Which of the following statements are not correct?a)In canonical struc...
 In NaCl the ions are not free in solid state but they are strongly bonded through electrostatic forces, hence is not a good conductor of electricity in solid state

A canonicalstructure is also known as a resonance structure, i.e. one of possibly more than one contributing structures that combine to produce the true, resonance hybrid structure. The arrangement of atoms remains the same.

Correct option is A and C.

Incorrect Statements:
a) In canonical structures, there is a difference in the arrangement of atoms.
c) NaCl being an ionic compound is a good conductor of electricity in the solid state.

Explanation:

a) In canonical structures, there is a difference in the arrangement of atoms.

- This statement is incorrect. In canonical structures, also known as resonance structures, there is no difference in the arrangement of atoms. Instead, the only difference lies in the placement of electrons.

- Resonance occurs when multiple equivalent Lewis structures can be drawn for a molecule or ion, differing only in the placement of electrons. The actual structure is considered as a combination or hybrid of all the resonance structures.

- For example, in the case of ozone (O3), the molecule can be represented by two resonance structures where the double bond alternates between the two oxygen atoms. However, the actual structure is a hybrid of these two resonance forms, with the double bond delocalized or spread out over all three oxygen atoms.

- Therefore, the arrangement of atoms remains the same in resonance structures, and the differences lie in the electron distribution.

c) NaCl being an ionic compound is a good conductor of electricity in the solid state.

- This statement is incorrect. Although NaCl is an ionic compound, it is not a good conductor of electricity in the solid state.

- Ionic compounds consist of a lattice of positive and negative ions held together by electrostatic forces. In the solid state, these ions are locked in place and cannot move freely. Therefore, ionic compounds do not conduct electricity in the solid state.

- However, when an ionic compound like NaCl is dissolved in water or melted, the ions become free to move and can conduct electricity. This is because the water molecules or the liquid medium allows the ions to separate and move, creating a pathway for the flow of electric current.

- In the solid state, NaCl and other ionic compounds are insulators rather than conductors.

- Metals, on the other hand, are good conductors of electricity in the solid state because they have delocalized electrons that are free to move throughout the metal lattice.

- Therefore, NaCl is not a good conductor of electricity in the solid state.

Root and StemDefinition of RootA root is an underground part of a plant that typically lacks nodes, leaves, and buds. It is responsible for anchoring the plant in the soil, absorbing water and minerals, and storing nutrients. Roots can be classified into two types: taproots and fibrous roots.Definition of StemA stem is the aboveground part of a plant that supports leaves, flowers, and fruits. It contains nodes, internodes, and buds. The primary functions of a stem are to transport water, nutrients, and sugars between the roots and the leaves, provide structural support, and facilitate the growth of the plant.Differences between Root and Stem1. Structure- Root: Roots are typically found underground and have no nodes or leaves. They have a central primary root, known as the taproot, from which smaller lateral roots branch out.- Stem: Stems are found aboveground and have nodes, internodes, leaves, and buds. They have a central main stem, known as the shoot, from which lateral branches and leaves arise.2. Function- Root: The main functions of roots are anchoring the plant in the soil, absorbing water and minerals, storing nutrients, and providing support.- Stem: Stems have several functions, including transporting water, minerals, and sugars between the roots and leaves, providing structural support, and facilitating growth and reproduction.3. Location- Root: Roots are typically found below the soil surface, although some plants have aboveground roots called aerial roots.- Stem: Stems are generally located above the ground, but they can also be partially or entirely underground.4. Growth- Root: Roots grow in length from the root tip and branches develop from the primary root.- Stem: Stems grow in height from the apical meristem located at the tip of the stem. This growth allows the plant to reach sunlight and maximize photosynthesis.5. Types- Root: Roots can be classified as taproots or fibrous roots based on their structure and branching pattern.- Stem: Stems can be classified as herbaceous or woody based on their texture and ability to undergo secondary growth.ConclusionIn summary, roots and stems are essential parts of a plant with distinct structures and functions. Roots are primarily responsible for anchoring the plant, absorbing water and minerals, and storing nutrients. Stems, on the other hand, support leaves, flowers, and fruits, transport substances throughout the plant, and provide structural support. Understanding the differences between roots and stems helps us appreciate the complexity and diversity of plant anatomy and physiology.
