What is the approximate length of the NN bond in nitrogen hydride (HNNH) using the table values?

1. 150 pm

2. 135 pm

3. 110 pm

4. 60 pm

5. 55 pm

6. 120 pm 

Solution

We’re being asked to approximate the length of the N–N bond in nitrogen hydride (HNNH).


Based on the given table of values, we have to determine the type of bond present in the structure of nitrogen hydride.


Draw the Lewis Structure of nitrogen hydride (HNNH):
