Passage / Comprehension

In general electronegativity increases from left to right in a period and decreases from top to bottom in a group. Pauling scale is the most widely used scale for electronegativity

The electronegativity of $B, C, N, O$ and F are 2.5, 3.0, 2.0, 3.5, 4.0 placed in a random order. If the electronegativity of $N$ is $x$ , then the value of $\frac{x}{2}$ is

Answer:

1.49

Solution:

EN order : B < C < N < O < F

2.0 2.5 3.0 3.5 4.0

Therefore, EN of N = 3.0, and $x /2 = 1.50$ .
