Find the CBSE Class 11 Chemistry Solved Practice Paper for the coming pre-board exam. These questions will not only help the students to prepare for exams in a better manner, but will also help them in understanding the depth with which a topic should be studied.

**Few sample questions from the Question Paper are given below:**

**Q. **Arrange the elements B, C, N, F, and Si, in increasing order of their non-metallic character.

**Ans. **In a periodic table, from left to right in a period the non-metallic character increases and from top to bottom in a group the non-metallic character decreases. Therefore, the increasing order of non-metallic character for the given elements is:

B < Si < C < N < F

**Q.** Calculate the molarity of NaOH in the solution prepared by dissolving its 8 g in enough water to form 500 mL of the solution.

**Ans.**

**Q.** Among NH_{3}, H_{2}O and HF, which would you expect to have highest magnitude of hydrogen bonding and why?

** Ans. **H-bonding in a molecule depends upon the electronegativity and the number of hydrogen atoms. The increasing order of electronegativity among nitrogen, oxygen and fluorine is N < O < F. But the extent of H-bonding follows the order: NH

** Q. **The order of reactivity among group 1 elements is Li < Na < K < Rb <Cs while that of group 17 elements is F > CI > Br > I. Explain.

** Ans. **The outermost cofiguration of the alkali metal is ns
