In electrophilic aromatic substitution reactions, the -CF3 group is . A) an activating group because it donates electron density through inductive stabilization
B) an activating group because it donates electron density through resonance
C) a deactivating group because it withdraws electron density through inductive destabilization
D) a deactivating group because it withdraws electron density through resonance

The equation below shows a chemical reaction. a + b + heat —> c + d according to the law of conservation of energy, which statement is true? a. the reactants absorb heat because they have less energy than the products. b. the products release heat because they have more energy than the reactants. c. the reactants generate heat because they have more energy than the products. d. the products require heat to form because they have less energy than the reactants.
