Module 1–6 Exams & Final Exam | 2025/2026
hydrocarbons - correct answerssimplest organic compounds; contain only carbon and
hydrogen; nonpolar
alkanes - correct answersorganic molecule that only consists of single bonds between
carbons; insoluble in water; -ane ending
tetravalent - correct answershaving a valence of four; carbon atoms
restricted rotation - correct answerswhen an isomer has a double bond between its
carbons
, cis isomer - correct answerstwo groups that lie on the same side of a double bond
trans isomer - correct answerstwo groups that lie on different sides of a double bond
halothane - correct answersgeneral anesthetic that is inhaled; 2-bromo-2-chloro-1,1,1-
trifluoroethane
addition - correct answerschemical reaction in which one molecule combines with
another to form a larger molecule with no other products
hydrogen - correct answersaddition reaction that needs a catalyst (Ni, Pt, Pd)
halogen - correct answersaddition reaction that involves this type of element; fast
reaction
combustion - correct answerschemical reaction that always involves oxygen
Markoviok's Rule - correct answersthe hydrogen atom goes to the double-bonded C
atom which already has the most hydrogen atoms; rich get richer
