The hydride that is NOT electron deficient is:
- a✓
- b
- c
- d
Strategy: Identify which hydride is NOT electron-deficient by comparing electron counts.
Step 1: Classifying Hydrides A hydride is electron-deficient if the central atom has fewer than 8 electrons in its valence shell:
- (Boron): B has only 3 valence e⁻; diborane is electron-deficient. ❌
- (Aluminium): Al has 3 valence e⁻; AlH₃ is electron-deficient. ❌
- (Gallium): Similarly electron-deficient. ❌
- (Silicon): Si has 4 valence e⁻ + 4 from H = 8 electrons — complete octet. It is an electron-precise (not electron-deficient) hydride. ✅
