Example:
The most common example of using acid anhydride salt as a catalyst is the preparation of Cinnamic acid using the Perkin reaction from benzaldehyde. In addition, the sodium salt of salicylaldehyde is heated with acetic anhydride to create coumarin

Definition: What is Perkin Reaction?
The Perkin reaction, also known as Perkin condensation, is an organic reaction which is used for the synthesis of α,β-unsaturated aromatic acid by the condensation of an aromatic aldehyde and an acid anhydride, in the presence of an alkali salt of the acid acting as a weak base. Generally, such type of reaction is only…

Example of Hoffmann bromamide degradation reaction
1. Preparation of aniline 2. Preparation of methylamine Hoffmann Bromamide Degradation Reaction Mechanism Hoffmann bromamide reaction mechanism can be explained in the following steps – Step 1: In this step primary amide reacts with sodium hydroxide. Hydroxide ion(anion) of NaOH attacks on a group of primary amides which results in deprotonation of primary amides and…

Hoffmann’s bromamide degradation reaction
As the name of the reaction suggests, Hoffmann’s bromamide degradation reaction was given by August Wilhelm Von Hoffmann. It is also known as the Hoffmann Rearrangement Reaction. This reaction is used to form primary amines. Let’s understand the name of the reaction first so that it will be easy for you to remember the reaction. …

Mathematical definition
The law can be written as: or= where This law describes how, under the same condition of temperature and pressure, equal volumes of all gases contain the same number of molecules. For comparing the same substance under two different sets of conditions, the law can be usefully expressed as follows:= The equation shows that, as the number of moles of gas increases, the…

Avogadro’s Law
Avogadro’s law, a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules. This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas. The law is approximately valid for real gases at sufficiently low pressures and high temperatures. The specific number of molecules in one…

Defining Complex Networks
In the previous lesson, you learned to create a trivial network and learned how to execute it and examine its output. The process for creating complex networks is similar to the process described above. Caffe2 provides a huge set of operators for creating complex architectures. You are encouraged to examine the Caffe2 documentation for a…

Creating Your Own Network
In this lesson, you will learn to define a single layer neural network (NN) in Caffe2 and run it on a randomly generated dataset. We will write code to graphically depict the network architecture, print input, output, weights, and bias values. To understand this lesson, you must be familiar with neural network architectures, its terms and mathematics used in them. Network Architecture…

Image Classification Using Pre-Trained Model
In this lesson, you will learn to use a pre-trained model to detect objects in a given image. You will use squeezenet pre-trained module that detects and classifies the objects in a given image with a great accuracy. Open a new Juypter notebook and follow the steps to develop this image classification application. Importing Libraries First, we import the…
