SCH4U Organic Chemistry Question
and answers rated A+ 2025
Substitution rxn - correct answer alkane/benzene + F2/Cl2/Br2 = alkyl/phenyl
halide + hydrogen halide **heat/UV**


Markovnikov's Rule - correct answer When adding H2O to an alkene, add the
H to the C w/ the most H's in the double/triple bond and the OH to the C w/
less H's. ("The rich get richer")


Halogenation (addition rxn) - correct answer alkene/alkyne + Br2/Cl2 = alkyl
halide (*breaks double/triple bond with no excess hydrogen halide)** room
temp**


Hydrogenation (hydrocarbons) - correct answer alkene/alkyne + H2 = alkane
(breaks double/triple bond) **catalyst**


Hydrohalogenation (Addition rxn) - correct answer alkene/alkyne + HCl/HBr =
alkyl halide (breaks double/triple bond) **room temp**


Hydration (addition rxn) - correct answer alkene/alkyne + HOH = alcohol
**H2SO4**


synthesis of nitrobenzene (substitution) - correct answer benzene + HNO3 =
nitrobenzene + HOH **H2SO4**


elimination (dehydration rxn) - correct answer alcohol = alkene/alkyne + HOH
**H2SO4** (reverse of hydration rxn)
