Chemical Bonding and Molecular Structure

11955 The number of electrons shared by each outermost shell of $N_{2}$ is

1

2

2

3

3

4

4

5

Explanation:

(b) Each nitrogen share $3$ electrons to form triple bond.

Chemical Bonding and Molecular Structure

11956 Which of the following substances when dissolved in water will give a solution that does not conduct electricity

1 Hydrogen chloride

2 Potassium hydroxide

3 Sodium acetate

4 Urea

Chemical Bonding and Molecular Structure

11957 Which of the following atoms has minimum covalent radius

1

B

2

C

3

N

4

S i

Explanation:

As we move along a period radius decreases and as we move down the group, radius increases.
Hence, $B (5) > C (6) > N (7)$ .
Also, $(r^{n} \propto \frac{1}{Z}$ along a period)

Chemical Bonding and Molecular Structure

11958 Boron form covalent compound due to

1 Small size

2 Higher ionization energy

3 Lower ionization energy

4 Both
