Daily Starter How are theses structures similar?

Introduction to Functional Groups About 200 yrs. ago, scientists believed that ONLY living organisms could synthesize carbon compounds, so they were classified as ORGANIC.

Hydrocarbons Hydrocarbons (are exactly as they sound), they are the simplest organic compound that contains only C & H. “Hydro” = Hydrogen Carbon…well…

RECALL Because carbon has _______ valence electrons, it can make _______ bonds. (look on your periodic table….now please)

Because carbon has _______ valence electrons, it can make _______ bonds.

Prefixes - MEMORIZE Meth = 1 Carbon Hex = 6 C Eth = 2 C Hep = 7 C Prop = 3 C Oct = 8 C But = 4 C Non = 9 C Pent = 5 C Dec = 10 C

YOU DRAW THEM! METHANE = CH4

YOU DRAW THEM! ETHANE = C2H6

YOU DRAW THEM! PROPANE = C3H8

YOU DRAW THEM! BUTANE = C4H10

YOU DRAW THEM! PENTANE = C5H12

YOU DRAW THEM! HEXANE = C6H14 Line angle Formula All C & H understood

YOU DRAW THEM! HEPTANE = C7H16

YOU DRAW THEM! OCTANE = C8H18

YOU DRAW THEM! NONANE = C9H20

YOU DRAW THEM! DECANE = C10H22

ISOMER When 2 or more molecules have the same chemical formula, but different structures. C4H8 C4H8

ISOMER When 2 or more molecules have the same chemical formula, but different structures. C4H8 2 methyl-Propane (Main chain = name) C4H8 Butane (Main chain = name)
