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.
![**Question 3:**
Select which of the following products would be made by the chemical transformation indicated below:
[Diagram of a chemical reaction]
- The diagram on the left shows a linear structure with a triple bond, representing an alkyne.
- An arrow points to the right towards a blank rectangle, indicating the transformation.
- Above the arrow, the text reads: "H₂ / Lindlar’s cat." which signifies the use of hydrogen gas and Lindlar catalyst for partial hydrogenation.
This setup suggests a reaction where an alkyne is transformed into a cis-alkene using hydrogen in the presence of Lindlar's catalyst, which selectively reduces the alkyne to an alkene without further reduction to an alkane. The expected product is a cis-alkene.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffe9fe32c-b492-41de-b627-5e5dec5bc081%2F68892337-b28e-4a47-a386-035a53b3eaec%2Fj442m1c_processed.jpeg&w=3840&q=75)
Lindlar Catalyst follows syn addition machanism means both hydrogen atom add to alkyne in same face
