The three electrophilic addition steps for the formation of cholesterol from squalene as per Equation 11-38 are to be drawn using curved arrow notation. Concept introduction: An electrophilic addition reaction step is one in which an electron-rich species attacks an electron-poor species to form a σ bond with it. An electron-rich species (nucleophiles) may be an atom with a lone pair, with or without a negative charge, or a π bond pair. Highly electronegative atoms like O and N that possess at least one lone pair can act as nucleophiles. An electron-poor species (electrophile) is an atom with an incomplete octet and a positive charge. These are typically a carbocation or a carbon attached to a highly electronegative atom like oxygen.
