Question

The hydrides of which group elements are examples of electron precise hydrides?

• A. Group 14 elements
• B. Group 13 elements
• C. Group 15 elements
• D. Group 16 elements

Hint:

Electron precise hydrides are characterized by having exactly enough electrons to form normal covalent bonds without any lone pairs on the central atom.

Answer 1

The Correct Option is A

- Electron precise hydrides are those in which the total number of valence electrons equals the sum of the bonding electrons around the central atom.
- Group 14 elements form typical electron precise hydrides like CH₄ (methane), where each hydrogen atom contributes 1 electron and carbon contributes 4, making a stable electron count of 8 around carbon.
