Identify the species that act as electrophiles from the following list: (P) R ₃ N (Q) : CCl ₂ (R) CH ₃^ (S) H ₂ O (T) H ₃ O ^ (U) Na ^
Options
- A(Q), (R), (T) and (U)
- B(Q), (R), (S), (T) and (U)
- C(Q) and (R)
- D(Q), (R), (S) and (T)
Correct answer
C. (Q) and (R)
Step-by-step solution
Electrophiles are electron-deficient species that have a tendency to accept an electron pair. (P) R ₃ N : The nitrogen atom has a lone pair of electrons, making it an electron-rich species. It acts as a nucleophile. (Q) : CCl ₂ : Dichlorocarbene has a central carbon atom with only 6 valence electrons. Being electron-deficient, it acts as an electrophile. (R) CH ₃^ : The methyl cation has a central carbon atom with 6 valence electrons. It is electron-deficient and acts as an electrophile. (S) H ₂ O : The oxygen atom
