JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
Number of electron deficient molecules among the following \(PH _{3}, B _{2} H _{6}, CCl _{4}, NH _{3}, LiH\) and \(BCl _{3}\) is ..... .
- A \(0\)
- B \(1\)
- C \(2\)
- D \(3\)
Answer & Solution
Correct Answer
(C) \(2\)
Step-by-step Solution
Detailed explanation
Electron deficient species have less than \(8\) electrons (or two electrons for \(H\) ) in their valence (incomplete octet) \(B _{2} H _{6}, BCl _{3}\) have incomplete octet.
