PPSC is a competitive exam that is conducted to select the deserving candidates for several vacant positions in government agencies and departments. The commission conducts the test of different natures according to the vacant positions. Ilmkidunya helps candidates to prepare for the PPSC exams. For every subject, the separate sections are designed and here at this page students are provided the chemistry subject test. This test is covering the VII part of the Chemistry syllabus that is arranged for the PPSC exam.
PPSC Chemistry Part VII Syllabus
The 7th part of the Chemistry syllabus is all about Nanochemistry. Nanochemistry is a combination of Chemistry and Nanoscience. The study is associated with the synthesis of building blocks. However, the study also covers some other related topics. Candidates who have done the preparation of this topic are suggested to attempt this test. While attempting this mock test you will be able to evaluate your knowledge level. The test is comprised of the questions that are so important according to the examination point of view. So, hopefully, we can say that after going through this test one can easily prepare this topic. However, you are also recommended to attempt a full book PPSC chemistry test for overall preparation.
