Correct answer: Option D: CH4- A. One 1s, one 2p
- B. One 2s, three 2p
- C. One 2s, two 2p
- D. One 2s, one 2p
Explanation: sp hybridization is the mixing of one s orbital and one p orbital from the same valence shell of an atom.
Correct answer: One 2s, one 2p- A. 25%
- B. 33.3%
- C. 50%
- D. 75%
Explanation: In sp2 hybrid orbital% of s character =1/3 x 100=33.3%In sp3% of p character = 3/4 x 100 = 75%
