Chemistry 12 Model Papers – Chapter 08 – Punjab Textbook Board

Here are ‘Insight Model Papers’ for chapter-8, Chemistry-12. As the chapter name ‘Aliphatic Hydrocarbons’ indicates, this is about open chain hydrocarbons, that is, alkanes, alkenes & alkynes. The chapter begins with the classification of aliphatic hydrocarbons and their IUPAC nomenclature. As such, this may be regarded as the most important chapter of organic chemistry because without understanding the thorough knowledge of naming the organic compounds, no further study is possible. The other topics dealt here are Kolbe’s electrolytic methods for the preparation of alkanes, alkenes & alkynes, halogenation of alkanes involving radical mechanism, Clemmensen’s reduction, Wolf-Kishner’s reduction, Sabatier-Sendern’s reactions, Markownikoff’s rule, Baeyer’s test, acidic behaviour of terminal alkynes etc.  

From examination point of view, this chapter has a weightage of 11 marks, comprising one long question for 4 marks, three short questions for 6 marks and one MCQ or multiple choice question.

The model papers given below are complete chapter tests that fall into the following three categories:

  • A – 19 Marks Tests
  • B – 30 Marks Tests
  • C – 40 Marks Tests

Type A tests contain 1 LQ, 5 SQs & 5 MCQs. These are meant for initial stage testing. Type B tests are a bit lengthy and contain 2 LQs, 8 SQs & 6 MCQs. The type C tests contain 3 LQs, 10 SQs & 8 MCQs. These are usually required at the middle and end stages of testing when writing stamina of the student is also on the focus.
