Name this type of bond fission.
Using single headed arrows, show the movement of electrons when a molecule of chlorine, Cl2, is exposed to UV light according the equation.
Cl2 → 2Cl•
Explain why a hydrogen ion, H+, can behave as an electrophile.
Propene, CH3CHCH2, can undergo electrophilic addition with hydrogen bromide, HBr, to form 2-bromopropane.
Figure 2 shows a partly completed mechanism. Use curly double headed arrows to complete the mechanism.
