Chemistry - CHEMICAL BONDING Question with Solution | TestHub
S₂F₂ exists in two structures:
Structure (I): The molecule has only 3 bonds, all of which are bonds. No d-orbital is used in hybridization or - bonding.
Structure (II): All F atoms are on the same sulfur atom, and it has one 3p – 3d bond.
Which of the following is/are isostructural with structure-I of :-
Options:(select one or more)
Answer:
Solution:
Structure (I) of S₂F₂ has only σ bonds and no π bonding or d-orbital involvement, giving a simple bent / open-chain structure (F–S–S–F type).
Species isostructural with it must also have single bonds only and similar bent/non-planar arrangement.
C₂H₂ (acetylene) is linear with π bonds → not isostructural.
H₂O₂ and O₂F₂ both have peroxide-type (X–O–O–X / X–S–S–X) bent structures with only σ bonds, matching structure (I).
N₂F₂ generally involves different geometry (planar with N=N character), so not fully isostructural.
