Which of the following structure of a molecule is expected to have three bond pairs and one
lone pair of electrons?
- A Tetrahedral
- B Trigonal Planar
- C Pyramidal
- D Octahedral
Answer & Solution
Correct Answer
(C) Pyramidal
Step-by-step Solution
Detailed explanation
For tetrahedral geometry:
No. of electron pair \(=4\)
Bond pair = 4
Lone pair = 0
For pyramidal geometry: No. of electron pair \(=4\)
Bond pair \(=3\)
Lone pair \(=1\)
For trigonal planar geometry: No. of electron pair \(=3\)
Total bond pair \(=3\)
Lone pair = 0
For octahedral geometry: No. of electron pair \(=6\)
No. of electron pair \(=4\)
Bond pair = 4
Lone pair = 0
For pyramidal geometry: No. of electron pair \(=4\)
Bond pair \(=3\)
Lone pair \(=1\)
For trigonal planar geometry: No. of electron pair \(=3\)
Total bond pair \(=3\)
Lone pair = 0
For octahedral geometry: No. of electron pair \(=6\)
