The monomers of lipids are called fatty acids. Draw the lipid monomer a fatty acid, labeling the hydrocarbon chain and the carboxyl end group. Be sure to show ALL of the atoms within the molecule (there are several different fatty acids in living things including oleic acid and stearic acid, each with a unique molecular formula). Do not give handwriting solution.

Predict te organic product that forms in the reaction below: H Xy+ OH H+ OH H+ Note: You may assume you have an excess of either reactant if the reaction requires more than one of those molecules to form the product. In the drawing area below, draw the skeletal ("line") structure of the missing organic product X. Click and drag to start drawing a structure.

C5H12 has 3 structural isomers C6H14 has 5 structural isomers C7H16 has 9 structural isomers. I get what a structural isomer is, but when I see a statement like the 3 statements above, I wonder if there is a way I can figure out how many structural isomers something has?  I'm in CHEM 2.  We didnt talk about that but when I see a slide he has telling me this, and I am wondering what to take from the slide...hmmm.

F3C - T SOH Br3C III Rank the compounds (shown below) in order of increasing acidity. H3C ОН II ОН A) | < ||| < || B) ||| < || < | C) || < III < | D) ||| < | < || E) II < I < |||

Determine the structures of the missing organic molecules in the following reaction: Y II OH X + H₂O H+ H* OH Note: Molecules that share the same letter have the exact same structure. In the drawing area below, draw the skeletal ("line") structures of the missing organic molecules X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. Click and drag to start drawing a structure. C X :0 Ś m c+

The name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water.") The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms (see sketch at right). But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this. Suppose you had  300.g  of ordinary table sugar, which chemists call sucrose, and which has the chemical formula  C12H22O11 . Calculate the maximum mass of water you could theoretically extract. Be sure your answer has a unit symbol, and round it to the correct number of significant digits.

4 Why would the chemical equation 1 B2(CO3)3 →1 B2O3+3 CO2 be considered “wrong”?
