Proteins and Their Classification

Science > Chemistry > Biomolecules > Proteins and Their Classification The name protein (proteios Greek  = pre-eminent or first) was first suggested, in 1838, by a Swedish chemist Berzelius to a Dutch chemist Mulder, who referred it to the complex organic nitrogenous substances found in the cells of the living beings. They are naturally occurring nitrogenous polymers of different alpha-amino […]

Types of Chemical Reactions

In this article, we shall study the types of chemical reactions. Before understanding the types of chemical reactions, let us study the meaning of the terms “a physical change” and “a chemical change” Physical Change: A change in which only the physical properties of a substance are changed is called a physical change. In a […]

Formation of Differential Equations – 01 (Single Arbitrary Constant)

In this article, we shall study to form a differential equation by eliminating a single arbitrary constant from the given relation. Example – 01: xy = c Solution: Given xy = c ……….. (1) Differentiating both sides w.r.t. x x + y(1) = 0 ∴ x + y = 0 This is the required differential Equation […]

Maximum and Minimum Value of Function

In this article, we shall find the maximum and minimum value of the given function. Example – 01: If x + y = 3 show that the maximum value of x2 y is 4 Solution: Given x + y = 3 hence y = 3 – x ∴  x2 y = x2(3 – x) = 3×2 – x3 […]

Forward Differences 01

In this article, we shall study to prepare the forward difference table from the given data. Example – 1: If f(x) = x2 + x + 1, construct a forward difference table by taking x = 0, 1, 2, 3, 4, 5 i.e. 0(1)5. Hence find Df(o), D2f(1) and D3f(2). Solution: Given f(x) = x2 […]

Reactions of Alkenes

In the last article, we have studied methods of preparation of alkenes. In this article, we shall study the reactions of alkenes Stability of Alkenes: The stability of alkenes is measured in terms of its heat of hydrogenation. The heat of hydrogenation of an alkene is defined as the amount of heat evolved when one […]

Preparation of Alkenes

In the last article, we have studied what are alkenes and isomerism in them. In this article, we shall study different methods of preparation of alkenes. Preparation of Alkenes By Dehydration of Alcohols: Alcohols on heating in the presence of dehydrating agents Iike concentrated sulphuric acid or phosphorous pentoxide or anhydrous alumina etc. undergoes a loss […]

Alkenes: Introduction

In this article, we shall learn about alkanes, isomerism in alkenes. Compounds containing carbon and hydrogen only are called hydrocarbons. Examples: Methane (CH4), Ethane (C2H6), Benzene (C6H6), etc. Aliphatic Hydrocarbons: The hydrocarbons in which carbon atoms are joined form an open chain are called aliphatic hydrocarbons. Examples: Methane (CH4), Ethane (C2H6), etc. Aliphatic hydrocarbons are […]

Binomial Distribution

Science > Mathematics > Statistics and Probability > Probability > Binomial Distribution In this article, we shall study to solve problems of probability based on the concept of the binomial distribution. Example – 01: An unbiased coin is tossed 5 times. Find the probability of getting a) three heads b) at least 4 heads Solution: […]
