Igcse Model Questions Vol1 2023 Chemistry Question 26
Practice objective / multiple choice question 26 from the 2023 Igcse Model Questions Vol1 Chemistry examination.
Among the non‑metals nitrogen (N), chlorine (Cl) and fluorine (F), the following data are given: - Electronegativity (Pauling scale): N = 3.0, Cl = 3.2, F = 4.0. - The highest oxidation state each element attains in its common oxide is: N (+5 in \(\mathrm{N_2O_5}\)), Cl (+5 in \(\mathrm{Cl_2O_7}\)), F (does not form an oxide). Acidic character of a non‑metal oxide increases with both higher electronegativity and higher oxidation state of the central atom. Which of the three elements forms the most acidic oxide? Give the molecular formula of that oxide.
