Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.
![**Drawing Organic Molecules Using Chemical Drawing Tools:**
In this tutorial, you will learn how to draw an organic molecule using various chemical drawing tools available on the platform.
The molecule depicted here can be drawn by following these steps:
- **Structure Overview:**
- The molecule includes a central carbon (C) atom.
- This carbon is double-bonded to an oxygen (O) atom (indicated by a double line).
- The carbon is single-bonded to two methyl (CH₃) groups.
- Additionally, the carbon is bonded to a hydroxide ion (OH⁻) with a single bond.
- **Steps to Draw the Molecule:**
1. **Select Tools:**
- Use the Tools toolbar to select the type of bond (single or double).
- Use the Atoms toolbar to select the types of atoms (C, O, H).
- Access the Advanced Template toolbars for any additional configurations such as charges.
2. **Draw Bonds and Atoms:**
- Start by placing the central carbon (C) atom on the canvas.
- Draw a double bond (two parallel lines) to an oxygen (O) atom.
- Attach two single bonds to two separate carbon atoms (CH₃ groups).
- Draw another single bond connecting to an OH⁻ group.
3. **Add Charges and Lone Pairs:**
- Include the lone pairs on the oxygen atom if necessary.
- Incorporate any charges by selecting the appropriate options from the toolbar.
Follow these simple steps to accurately draw the organic molecule on the canvas. Make sure that the single bond is selected by default, and adjust the bond type as you proceed through each step. This exercise will help you familiarize yourself with the usage of chemical drawing tools essential for representing chemical structures in a clear and precise manner.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcdfb37fd-3e7e-4c5b-b9de-8b4cda26a712%2F766f5cb7-2380-41f3-a39d-7b6f2d5321fd%2F093amw5_processed.png&w=3840&q=75)

**Title: Nucleophilic Substitution Reaction Example**
---
**Figure Description:**
The figure illustrates a nucleophilic substitution reaction mechanism. It includes the molecular formula and the electron movement in the reaction. This specific example showcases an ethyl bromide molecule (CH₃CH₂Br) and an ammonia molecule (NH₃) as the nucleophile.
1. **Ethyl Bromide (CH₃CH₂Br):**
- The molecule is shown with a carbon (C) bonded to three hydrogen (H) atoms and a carbon bonded to a bromine (Br) atom.
- There are lone pairs of electrons on the bromine atom indicating its high electronegativity.
2. **Ammonia (NH₃):**
- Ammonia is depicted with a nitrogen (N) atom bonded to three hydrogen (H) atoms and possessing a lone pair of electrons.
3. **Reaction Mechanism:**
- The lone pair of electrons on the nitrogen atom in NH₃ attacks the carbon atom bonded to bromine in CH₃CH₂Br.
- This electron movement is indicated by a curved arrow starting from the lone pair on NH₃ and pointing towards the carbon atom (CH₃CH₂) in CH₃CH₂Br.
- As the nucleophilic attack occurs, the bond between the carbon and bromine in CH₃CH₂Br breaks, releasing a bromide ion (Br⁻).
