Chemistry Class 12 Semester 2

Chemistry Class 12 Semester 2

 Entering the science major in grade 12, you will find learning chemistry. So Chemistry is a branch of science within the family of sciences that will study matter, its properties, structure, changes in response and energy that accompanies such changes. Maybe not many Indonesian students are interested in chemistry, because it is difficult and confusing.

 Although, if you are capable of studying chemistry with discipline, the opportunity to understand such subjects will be much easier. So, students can look for issues about chemistry in grade 12, before the teacher explains. Later, if there is something you don't understand, then you can ask your teacher.

 Chemistry Class 12 Semester 2

 Entering semester 2 in grade 12, you should concentrate more on studying if you want to enter a top university. For science majors, try to concentrate on studying some core subjects, such as Mathematics, Physics, Biology and Chemistry. If you want to understand chemistry learning In semester 2, here are some of the materials that will be taught by teachers in grade 12;

 CHAPTER 4 Carbon Compounds

 Chapter 4 or the first chapter in this second set you will learn about carbon compounds. So the chemistry subject with the chapter on carbon compounds consists of carbon, hydrogen, nitrogen, oxygen and other organic elements. Carbon is the largest component in this compound and is due to the peculiarity of the carbon atom.

 In the chapter on carbon compounds, you will study some of the components in such matter, such as the following;

 Learn about alcohols, ethers, aldehydes, ketone acids, carboxylic acids, and esters.

 You will also learn about the response of alcohols, ethers, aldehydes, ketone acids, carboxylic acids, and esters.

 Students will understand isomers and the uses of inherent alkanes.

 The carbon you study in this material can form single, double, and triple bonds. The feature of this is that carbon atoms are able to form carbon chains.

 CHAPTER 5 Benzene

 Then in chapter 5, you will learn about the nature of benzene and its uses. Benzene is known as the chemical formula and is an organic chemical compound in the form of a colorless and flammable liquid. In addition, this benzene also has a sweet smell.

 In benzene consists of 6 carbon atoms that make up a ring with one hydrogen atom bonded to each one carbon atom. So you will learn about the nature of benzene and its uses in chapter 5 of semester 2 for studying chemistry.

 CHAPTER 6 Polymers

 Next, in chapter 6, polymers or variations of polymers and their uses also include the chemicals that you will learn in grade 12. Polymers are one of the materials that are often applied in people's lives. So this polymer is in the form of long and repeating molecular chains and is the result of an operation called polymerization.

 In chemistry class 12 semester 2, you learn about the various polymers and their uses. It is desirable that students have been able to understand and recognize the benefits of this polymer according to its use.

 CHAPTER 7 Macromolecules

 Then in chapter 7 you will learn about macromolecules. A macromolecule is a molecule of very large size and chemical processing to refer to a nucleic acid, lipid, or carbohydrate. These macromolecules are generally a combination of several units, so their structure tends to be loop. In the chapter on macromolecules you will learn about carbohydrates, proteins, and fats.

 Class 12 chemistry material in semester 2 will study about 4 chapters ranging from carbon compounds, benzene, polymers, and macromolecules. Make sure you have learned about such material, so that when the teacher explains, you can understand better.
