Question

The correct order of ΔiHs among the following elements is

Options

• Bc < Be < C < O < H

• B < BC < C < N < O

• Be < B < C < N < O

• Be < B < C < O < N

Answer 1

Bc < Be < C < O < H

Explanation:

The Δ₁H_i value increases over time, but N with a more symmetrical configuration has a higher Δ₁H_i value than 0. Because of the same reason, be has a higher Δ₁H_i value than B.
