Please enter one of the numbers found on this handout. Would you consider the reaction to be endothermic or exothermic as drawn? Tip: Think in terms of stability and energy. Which side of the equilibrium is favored? That side would be lower in energy and more stable. exothermic endothermic Alkyl halides are very often used as electrophiles in reactions. Select all that apply. The CBr bond is polarized. The carbon of the CBr bond is partial positive. None of the above apply. The bromide anion is extremely stableot basic so it can exist on its own easily once the nuc replaces the halogen.
