Consider the reactions :
(i) S + O₂ → F
(ii) F + PCl₅ → H + POCl₃
(iii) HCOOH + conc. H₂SO₄ → I + H₂O
Additional information : F and H are sulphur-containing compounds but I is not ; I is a poisonous gas of density 1.25 g/L at 1 atm, 0 °C.
Calculate the sum of the total number of sigma bonds per molecule of F, H and I. [C = 12, O = 16, S = 32, Cl = 35.5]
Answer:
6
Solution:
M(I) = 1.25 × 22.4 = 28 g/mol → I = CO (1 σ). F = SO₂ (2 σ). H = SOCl₂ (S=O + 2 S-Cl = 3 σ). Sum = 2 + 3 + 1 = 6.
