function introduction

Alcohols, phenols, ethers, aldehydes, ketones and carboxylic acids are compounds with functional groups containing oxygen. An alcohol contains one or more hydroxyl (OH) groups(s) attached to aliphatic carbon atom(s). For e.g., ethyl alcohol formula CH 3 , CH 2 , OH is an alcohol. A phenol..

Introduction - All organisms require energy in order to stay alive. Energy is utilised to do the various bodily functions such as breathing, ingesting and digesting food, excreting, reproducing, locomotion, etc. Energy is obtained from food. Thus the process of intake of food is..

Introduction to Differentiation - After having studied functions, limits and continuity in the previous chapter, we shall further divide the class of continuous functions into two sub classes, derivable and non-derivable.After having studied functions, limits..

Introduction - The steam engine uses the power generated from steam pressure to move. Coal is used in furnaces to heat water in the boiler to generate steam. Steam pressure makes the wheels of the engine move. As coal is burnt, smoke is emitted and ash is left behind in the furnace. Smoke..

Introduction - Apart from air, the most abundant substance on the earth is water. Humans need water for drinking, bathing, sanitation, washing, cooking etc. Modern agriculture, industry, transport, power generation, civic facilities etc., cannot exist without water. Our body needs water f..

Types of Neurons - Based on their structure and function, the neurons are classified into three typ..

They consist of repeat units of monosaccharides or their derivatives. These units are held by glycosidic bonds. These carbohydrates liberate large number of monosaccharide molecules on hydrolysis. They are colorless and tasteless. So, they are called non-sugars. They are concerned with two im..

Introduction - Health is considered to be the state of perfect functioning of body and mind, unhindered by diseases. Disease is the malfunctioning of the organism or part of it due to infection, inherent weakness or environmental stress, that upsets the normal physiological ..

Functional Derivatives Of Carboxylic Acids - Introduction - Replacement of hydroxyl group in carboxylic acids with a halogen, carboxylate, alkoxy or amino group gives functional derivatives of carboxylic acid known as acyl halides, acid anhydrides, esters or amides res..

Introduction - An equation containing the trigonometrical functions of an unknown quantity is termed as a trigonometrical equation , which holds for some values (and not for all values) of the quantities involved. The value, that satisfies the equation are called the roots . The..
