Canvas Classes · Accepted Answer

Step 1 — Check isoelectronic nature:

| Species | Electrons |
|---------|----------|
|  | C(6) + 4H(4) = 10 electrons |
|  | N(7) + 4H(4) − 1 = 10 electrons |
|  | B(5) + 4H(4) + 1 = 10 electrons |

All three have 10 electrons → isoelectronic ✓

Step 2 — Check geometry:

| Species | Bonds | Lone pairs | Shape |
|---------|-------|-----------|-------|
|  | 4 | 0 | Tetrahedral ✓ |
|  | 4 | 0 | Tetrahedral ✓ |
|  | 4 | 0 | Tetrahedral ✓ |

All three are tetrahedral ✓

Answer: Option (2) — Isoelectr
