Chem 219: Module 2 Exam with 100% Correct Solutions What are hydrocarbons? - Answer -Molecules composed of only the elements carbon and hydrogen What are the two major classes of hydrocarbons? - Answer -Aromatic (benzene) and aliphatic (alkanes, alkenes, alkynes) What is the main source of hydrocarbons? - Answer -Fossil fuels like coal, petroleum, and natural gas obtained by mining and drilling. What are Alkanes? - Answer -They are saturated hydrocarbons because their skeleton is only comp...

Chapter 1 Carbon and Its Compounds CHECKPOINT PROBLEMS Practice Problem 1.1 a) S — 1s2 2s2 2p6 3s2 3p4 b) Cl — 1s2 2s2 2p6 3s2 3p5 c) Na+ — 1s2 2s2 2p6 1-2 Copyright © 2018 Nelson Education Limited Practice Problem 1.2 a) Count valence electrons. Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence electrons. Build a bas...

how many bonds does carbon have? - 4!!!!!! What is the geometry of a carbon with four single bonds? - Tetrahedryl What are the angles of a carbon with single bonds? - 109.5 Which compounds are saturated? - Alkanes (single bonded carbons) are saturated. Which compounds are unsaturated? - Alkenes (double bonds) and alkynes (triple bonds) How do you name an alkane? - determine the longest continuous chain of carbons, box it. we call this the parent chain. then you n...
