CBSE Class 10 - Case Study Based Question

Study the following case study and answer the questions given below:

Water is a simple molecule consisting of one oxygen atom bonded to two different hydrogen atoms. Because of the higher electronegativity of the oxygen atom, the bonds are polar covalent (polar bonds). The oxygen atom attracts the shared electrons of the covalent bonds to a significantly greater extent than the hydrogen atoms. The molecule has a bent structure, the H—O—H bond angle is about 105°.

Questions:

Q1. Between Hydrogen and Oxygen, which is more negative?

Q2. What is the shape of water molecule?

Q3. What type of type of bonding is there in a water molecule?

Q4. Draw the electron dot structure of water molecule

Q5. The H—O—H bond angle in water molecule is?

Answers:

1. Oxygen

2. Bent structure

3. Covalent bonding

4. 

5. 105°
