Spirtlər: What Are They and Why Are They Important?




Spirtlər are a group of organic compounds that have a hydroxyl group (-OH) attached to a carbon atom. They are widely used in various fields, such as medicine, food, industry, technology, environment, and energy. In this article, we will explore what spirtlər are, how they are classified, what their physical and chemical properties are, how they are obtained, and what their applications and uses are. We will also discuss the benefits and drawbacks of spirtlər, as well as their future prospects and challenges.


Introduction




What are spirtlər and how are they classified?




Spirtlər are organic compounds that have a hydroxyl group (-OH) attached to a carbon atom. The general formula for monospirtlər, which are the simplest type of spirtlər, is CnH2n+1OH. For example, methanol (CH3OH) and ethanol (C2H5OH) are monospirtlər. Spirtlər can also have more than one hydroxyl group attached to different carbon atoms, forming diaspirtlər, triaspirtlər, or polyaspirtlər. For example, ethylene glycol (C2H4(OH)2) is a diaspirit, glycerol (C3H5(OH)3) is a triaspirit, and pentaerythritol (C5H12O4) is a polyaspirit.




spirtlər




Spirtlər can be classified according to the position of the hydroxyl group on the carbon chain. If the hydroxyl group is attached to the end carbon atom, the spirit is called a primary spirit. If the hydroxyl group is attached to a middle carbon atom that is connected to two other carbon atoms, the spirit is called a secondary spirit. If the hydroxyl group is attached to a middle carbon atom that is connected to three other carbon atoms, the spirit is called a tertiary spirit. For example, propanol (C3H7OH) can exist as either 1-propanol (CH3CH2CH2OH), which is a primary spirit, or 2-propanol (CH3CHOHCH3), which is a secondary spirit.


What are the physical and chemical properties of spirtlər?




The physical and chemical properties of spirtlər depend on the number and position of the hydroxyl groups, as well as the length and structure of the carbon chain. Some of the common physical properties of spirtlər are:


  • The boiling point of spirtlər increases with the molecular weight and decreases with the branching of the carbon chain. This is because spirtlər can form hydrogen bonds with each other, which increase the intermolecular forces and require more energy to break. For example, ethanol (C2H5OH) has a higher boiling point than ethane (C2H6), but lower than 1-propanol (C3H7OH).



  • The solubility of spirtlər in water decreases with the length of the carbon chain and increases with the number of hydroxyl groups. This is because the hydroxyl group can form hydrogen bonds with water molecules, which increase the solvation and decrease the entropy. For example, methanol (CH3OH) is completely soluble in water, but octanol (C8H17OH) is barely soluble.



  • The density of spirtlər is lower than that of water, which means that spirtlər float on water. This is because the carbon atoms in spirtlər are less dense than the oxygen atoms in water. For example, the density of ethanol (C2H5OH) is 0.789 g/mL, while the density of water is 1.00 g/mL.



Some of the common chemical properties of spirtlər are:


  • The acidity of spirtlər increases with the electronegativity of the substituents attached to the carbon atom that bears the hydroxyl group. This is because the more electronegative substituents can withdraw electron density from the carbon-oxygen bond, which makes it easier to lose a proton. For example, trifluoroethanol (CF3CH2OH) is more acidic than ethanol (C2H5OH), which is more acidic than methanol (CH3OH).



  • The oxidation of spirtlər involves the removal of hydrogen atoms from the carbon atom that bears the hydroxyl group, forming carbonyl compounds such as aldehydes, ketones, carboxylic acids, or esters. The oxidation of spirtlər can be done by various agents, such as oxygen, potassium permanganate, or chromic acid. For example, ethanol (C2H5OH) can be oxidized to acetaldehyde (CH3C=O), ethanoic acid (CH3C(=O)OH), or ethyl acetate (CH3C(=O)OCH2CH3). The oxidation of spirtlər is easier for primary spirtlər than for secondary or tertiary spirtlər.



  • The dehydration of spirtlər involves the removal of a water molecule from two hydroxyl groups, forming alkenes or ethers. The dehydration of spirtlər can be done by heating with an acid catalyst, such as sulfuric acid or phosphoric acid. For example, ethanol (C2H5OH) can be dehydrated to ethene (C2H4) or diethyl ether (C2H5OCH2C2H5). The dehydration of spirtlər is easier for tertiary spirtlər than for primary or secondary spirtlər.



The esterification of spirtlər involves the reaction of a hydroxyl group with a carboxylic acid group, forming an ester and water. The esterification of spirtlər can be done by heating with an acid catalyst, such as sulfuric acid or hydrochloric acid. For example, ethanol (C2H5) can be esterified with ethanoic acid (CH3</ [assistant](#message) COOH) to form ethyl ethanoate (CH3COOC2H5) and water. The esterification of spirtlər is reversible and depends on the equilibrium between the reactants and products.</li What are the main sources and methods of obtaining spirtlər?

For example, ethanol (C2H5OH) is produced by the fermentation of sugars by yeast, methanol (CH3OH) is produced by the decomposition of wood, and glycerol (C3H5(OH)3) is a component of animal fats and vegetable oils.



  • Synthesis from hydrocarbons: Spirtlər can be synthesized from hydrocarbons, such as alkanes, alkenes, or alkynes, by adding water or oxygen across the carbon-carbon bonds. For example, ethene (C2H4) can be hydrated to ethanol (C2H5OH) by using an acid catalyst, and acetylene (C2H2) can be oxidized to acetaldehyde (CH3C=O) by using a copper catalyst.



  • Synthesis from carbonyl compounds: Spirtlər can be synthesized from carbonyl compounds, such as aldehydes, ketones, or carboxylic acids, by reducing the carbon-oxygen double bond. For example, acetaldehyde (CH3C=O) can be reduced to ethanol (C2H5OH) by using hydrogen gas and a metal catalyst, and ethanoic acid (CH3C(=O)OH) can be reduced to ethanol (C2H5OH) by using lithium aluminium hydride.



  • Synthesis from halogenoalkanes: Spirtlər can be synthesized from halogenoalkanes, such as chloroalkanes or bromoalkanes, by replacing the halogen atom with a hydroxyl group. For example, chloroethane (C2H5Cl) can be converted to ethanol (C2H5OH) by using sodium hydroxide solution.
