Prerequisites
In recent years a tendency is observed about difficulty and inability of students to work with text books or other literature. There is an inability in many students to draw conclusions from important scientific content, essential, to give the basic concepts, establish logical connections between them, and make correct judgments, to express definitions. For this reason, teachers need to dictate the most important, it takes a long time, the students record mechanically, but it unfortunately makes training quite "dry" and uninteresting. By tutorial in organic chemistry, students, instead of textbooks during the lesson, learn information of a new quality. Many students’ interest in science declines and fewer students buy their textbooks, so this site replaces the role of the textbook.
Content
The tutorial examines hydrocarbons as the most important class of organic compounds, and provides information about some of their derivatives such as alcohols are discussed. There is a short review of alkanes, alkenes and alkynes without focusing on their dissemination and practical implementation. The great theoretical, biological and practical importance of carbohydrates make them interesting for students and therefore are described in detail.

Objectives
By this self-tutorial students not only receive information but also, and transformed from passive recipients of foreign knowledge into active constructors of their own knowledge.
In the self-tutorial the information provided is not only used as a tool but as a primary means for acquiring knowledge. The demonstrated formulae illustrate the teacher’s lecture and the impact on the students is greater.
Applicability in teaching
This site is suitable for students who need to acquire a minimum knowledge of organic chemical compounds.
This way of work creates conditions for sharing thoughts and conversations on issues discussed, and increases the opportunities for acquiring new information.
The role of the teacher is to advise students actively in solving the tasks of the test, and thus to individually help each student solve their own problems without disturbing the others. So the teacher is most useful and successful in the education of all students in class.

Advantages
At certain moments of the lesson each frame is held as necessary The images complement the speech of the teacher. The tasks in the test explicitly demonstrated and eliminate any excuses for student misunderstanding . The vizualization of the material is improved immensely and it is extremely important for more complex theoretical issues. The proposed computer test allows obtaining feedback in order to diagnose deficiencies and self-correction of the students. It provides impact on more senses, develops abstract thinking, saves time, increases the emotional background in the classrooms and enhances the interest in the subject.
However the site has several major drawbacks. It gives too elementary knowledge that are appropriate for a limited number students. There is no description of many of the derivatives of hydrocarbons and the students have no accurate picture of their diversity. The test is only one with limited number of questions. There is not a word about the practical application of hydrocarbons and their derivatives.
