HW Review: Part B1 #2

Defining, Naming, and Describing Organic Compounds (Tables P &O)

1. Organic Compounds - have carbon atoms (see pics in table Q and R)2. Hydrocarbons contain C and H only3. To name a hydrocarbon, (a)The prefix is from the # of carbon atoms (Table P)(b)The suffix is from the # bonds between carbons (Table Q)(c) If there is a “functional group”, the beginning of the name tells the lowest # carbon that the functional group is attached to.

1. Name this hydrocarbon: _______________

2. Circle the correction name:(a) 1-chlorobutane(b) 2-chlorobutane(c) 3-chlorobutane(d) 4-chlorobutane

Empirical vs Molecular FormulaMolecular Formula: tells how many atoms are in a covalent compound(note: “Molecular Bonds” are “Covalent Bonds.” Molecular Formula is also called “chemical formula”

Ex: water is H2O. Butane is C4H 10

Empirical Formula: tells the lowest ratio of atoms in a molecule (after reducing by the GCF)

Ex Butane’s molecular formula is C4H 10 but it’s empirical formula is C2H 5

1. Write the empirical formula of C6H12 _____________

2. Which choice is both a molecular formula and an empirical formula?(a)C2H4 (c) C6H14

(b)H2O2 (d) CO2

Saturated vs Unsaturated HydrocarbonsSaturated Compounds: Have only single bonds between carbon atomsEx: alkanesUnsaturated Compounds: Have double or triple bonds between C atomsEx: alkenes and alkynes

1. Is C4H10 saturated or unsaturated?

2. Why is ethene unsaturated?

Student A: “Because there is more than one bond”

Student B: “There are double and triple bonds”

Student C: “The is more than one bond between the carbon atoms”

What happens?

Functional Groups (Table R)Functional Groups are atoms or a group of atoms in organic molecules that are NOT C and HLook at the examples on Table R

1. Which atom must all organic compounds have?(a) O (c) Cl(b) C (d) N

2. How many covalent bonds does each atom make?

Carbon (C) __________

Hydrogen (H) __________

Oxygen (O) __________

Nitrogen (N) __________

Fluorine (F) ___________
