- \( B, Al, Ga \)
- \( C, Si, Ge \)
- \( N, P, As \)
- \( B, C, N \)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Electron-Precise Hydrides
Electron-precise hydrides are covalent compounds in which all valence electrons participate in bonding, forming stable molecules.
Step 2: Identifying Suitable Elements
Elements from Group 14 (Carbon Family) form electron-precise hydrides:
\[
\text{CH}_4, \text{SiH}_4, \text{GeH}_4
\]
These obey the octet rule, filling valence shells.
Conclusion
Thus, the correct answer is:
\[
C, Si, Ge
\]
