Alkanes, which have only single bonds between their carbon atoms, are saturated hydrocarbons.They are chemically least reactive.They are also called paraffin, as they have no affinity (minimum affinity)towards chemical changes (parum=little; affins=affinity).However, under suitable conditions, they undergo substitution reactions. As an antiseptic to sterilize wounds and syringes in hospitals. Figure 05: Electrophilic substitution of NO2+ to benzene. Addition reactions and substitution reactions are types of organic reactions. Physical properties: Physical state/colour and odour: Pure ethanol is a colourless liquid having a pleasant smell and a burning taste.Boiling and Freezing points: It is a volatile liquid with a boiling point of 78.1°C, and freezing point is 118°C.Density: Ethanol is lighter than water as its density is 0.79 g ml-1 at 293 K.Solubility: Ethanol is miscible with water in all proportions, due to the formation of hydrogen bonds with water molecules.Ethanol containing 5% water is called rectified spirit and containing 0% water is called absolute alcohol. In the above image, “H2O“ is a nucleophile and it has lone electron pairs on the oxygen atom. H. Ethanol when heated with excess of concentrated sulphuric acid at 443 K, gets dehydrated to give ethene. The key difference between addition and substitution reaction is that the addition reaction is a chemical reaction that forms a large molecule from two or more small molecules whereas the substitution reaction is a chemical reaction in which atoms or functional groups replace the atoms or functional groups of a molecule.. Chemical reactions are the changes in the matter by chemical means. Addition reaction is any of a class of chemical reactions in which an atom or group of atoms is added to a molecule. Addition reactions and substitution reactions are types of organic reaction which type of reaction is shown by: i) Ethane (Substitution reaction) ii) Ethene (Addition reaction) Jan 14,2021 - Define Addition Reaction and Substitution Reaction.?
