Which of the following is not a correct statement? [2006]a)The can on ...
Explanation:
Option B is not a correct statement. It is false because not every AB5 molecule has a square pyramidal structure.

Let's understand the other options:

a) The canonical structures have no real existence:
- Canonical structures are hypothetical structures that represent the resonance hybrid of a molecule.
- They do not represent any actual physical structure of the molecule.
- Therefore, option A is a correct statement.

b) Every AB5 molecule does in fact have square pyramidal structure:
- AB5 molecules have 5 bonding pairs and no lone pairs of electrons.
- These molecules can have different shapes like trigonal bipyramidal, square pyramidal, or linear depending on the repulsion between the bonding pairs.
- Therefore, option B is a false statement.

c) Multiple bonds are always shorter than corresponding single bonds:
- Multiple bonds have more electrons shared between the atoms than single bonds.
- The increased electron density between the atoms pulls them closer to each other, making the bond shorter.
- Therefore, option C is a correct statement.

d) The electron-deficient molecules can act as Lewis acids:
- Lewis acids are electron acceptors, and they can accept a pair of electrons from a Lewis base.
- An electron-deficient molecule has a partially filled valence shell and can accept electrons to complete its octet.
- Therefore, option D is a correct statement.

In conclusion, the correct answer is option B.

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.
