Draw a chain of 4 Carbon-atoms, and number them from 1 to 4. On Carbon-atom number 2 draw a sidechain consisting of a methylgroup (-CH3) AND a hydroxygroup (-OH). On Carbon-atom number 3 draw a sidechain consisting of a methylgroup (-CH3). Since every Carbon makes 4 bonds everything will be allright when you "fill in the blanks" with Hydrogen-atoms. Tine
Acetone (2-propanone, propanone, or other names) has CH3COCH3 as its chemical formula. But it shares that formula with propionaldehyde (propanal). The two chemicals are structural isomers, and they have clearly different chemical properties. That's why we have a scheme for the structural formula of an organic compound. Since we can't "draw" here, use the link to a nice picture of the structural formula of acetone. The information is provided by our friends at Wikipedia, where knowledge is free.
The structural formula for alcohols is R-OH, where R represents an alkyl group. Alcohols contain a hydroxyl (-OH) group attached to a carbon atom of an alkyl group. The specific structure will vary depending on the alkyl group attached to the hydroxyl group.
Difficult to draw here, but let's try to describe: Three methyl groups (CH3-) and one H- atom bonded to one central C atom, then you'll get something like this: . . . .H CH3-C-CH3 . . . .CH3

Acetic alcohol is a mixture, not a pure substance. You make it by mixing 3ml acetic acid with 100ml of "absolute alcohol," which is ethanol containing less than 1 percent water by weight. So...you could draw an acetic acid lewis diagram and an ethanol lewis diagram side by side.
draw a structural formula for organics, write a chemical formula (molecular formula or ionic formula) for simpler compounds.

An example of an expanded structural formula for a cyclic compound is cyclohexane, which is a six-carbon ring with all single bonds. The expanded structural formula would show all the carbon and hydrogen atoms in the ring, along with the single bonds between them.
To draw the structural formula for lactose, start with a glucose molecule. Attach a galactose molecule to the glucose molecule through a beta-1,4 glycosidic bond. This forms the disaccharide lactose.
You're going to feel silly: aminoethane hydrochloride. As to structural formula, those are difficult to draw here, but approximately CH3CH2NH2 * HCl. That "*" should actually be a dot. You might also see it as CH3CH2NH3+Cl-.
A hydrogen atom is typically represented simply as an "H" surrounded by a single dot to denote the one electron in its outer shell. This is the simplest way to draw a hydrogen atom in a structural formula.
The first step to drawing a structural formula is to determine the primary arrangement of atoms in the molecule. This involves identifying the types of atoms present and the connectivity between them. Once this is established, you can then start depicting the bonds between the atoms using appropriate chemical symbols and lines.

I don't know how to draw on here, but these are some diagrams: Lewis dot diagram: http://bilbo.chm.uri.edu/CHM112/lectures/Image1127.gif And just it's structure: http://wpcontent.answers.com/wikipedia/commons/thumb/f/fc/Acetic_acid_flat_structure.png/150px-Acetic_acid_flat_structure.png
