Match List I with List II:

List I (Species): A.  B. Acetylide anion C.  D.

List II (Geometry/Shape): I. Tetrahedral II. Linear III. Pyramidal IV. Bent

Choose the correct answer:

Canvas Classes · Accepted Answer

Step 1 — Determine geometry of each species:

A.  (hydronium ion): O has 3 bonds + 1 lone pair → 4 electron pairs → Pyramidal → III

B. Acetylide anion ( or ): C≡C with linear arrangement → Linear → II

C.  (ammonium ion): N has 4 bonds + 0 lone pairs → Tetrahedral → I

D. : Cl has 2 bonds + 2 lone pairs → 4 electron pairs → Bent → IV

Matching: A-III, B-II, C-I, D-IV

Answer: Option (3)
