  • Question 6/10
    1 / -0
    Electrophile is:
    Solutions
    In chemistry, an electrophile (literally electron lover) is a reagent attracted to electrons. Electrophiles are
    positively charged or neutral species having vacant orbitals that are attracted to an electron rich centre. It
    participates in a chemical reaction by accepting an electron pair in order to bond to a nucleophile. Because
    electrophiles accept electrons, they are Lewis acids (see acid-base reaction theories). Most electrophiles are
    positively charged, have an atom that carries a partial positive charge, or have an atom that does not have
    an octet of electrons.
    In AlCl ALuminium has vacant p orbital so it can accept electron to fill it's octet completely.
    Hence, option C is correct
