Which of the following is an electrophile?

Electron deficient species or electron acceptors are called electrophiles. Electrophiles are electron-deficient species that are attracted to an electron-rich center. Electrophiles are often positively charged as a result of possessing an atom with a positive charge or an atom that does not have an octet of electrons. Out of the given species, :CCl2 (dichlorocarbene), has only 6e⁻ with carbon so, it is an electrophile.
