NCERT Solutions for Class 12 Chemistry chapter 7 The p-block elements

To help students to score well in their exams, here we are going to provide NCERT Solutions for Class 12 Chemistry chapter 7 The p-block elements. For the students of Class-12, Chapter 7 The p-Block elements is the most important chapter of chemistry because this chapter carries 8 precious marks out of 70 marks in the CBSE Board exam and also important for competitive exams like JEE, SRMJEEE, VITEEE, BITSAT, etc. In chapter 7 the p-block elements, there are 34 intext questions and 40 questions are given in the exercise. The step-by-step NCERT solutions are arranged in a sequential and logical manner which are prepared by our subject experts.

In class 11  we have learned that the p-block elements are placed from 13 to 18 groups of the periodic table. But in class 11 we only studied only two groups 13 and 14, so in NCERT Class 12 Chemistry chapter 7 the p-block elements, we are going to study groups from 15 to 18 of the periodic elements. In this chapter, we will learn the preparation, properties, and uses of dinitrogen, phosphorous, dioxygen, ozone, simple oxides, chlorine and hydrochloric acid and also study the uses of noble gases.

After completing Class 12 Chemistry chapter 7 the p-block elements students will be able to explain the general trends in the chemistry of elements of groups 15, 16, 17 and 18 and also able to explain the importance of these elements and their compounds in our daily life. The p-block elements are given in the following table-
