You can't draw a structural formula for methene because the prefix meth- means one carbon atom is present in the whole compound, and the suffix -ene means there is at least one double bond between only carbon atoms in the compound. If you added the other carbon atom necessary for the double bond it would change the name to ethene.
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-.
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
To determine the structural isomers of C6H14, first note that there are three main types of isomers for this molecular formula: straight-chain alkanes, branched-chain alkanes, and cycloalkanes. Count the total number of carbons and hydrogens to confirm they add up to 6 and 14, respectively. Then systematically draw out different possible arrangements of carbon atoms to generate all possible isomers within each category.
draw a structural formula for organics, write a chemical formula (molecular formula or ionic formula) for simpler compounds.

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.

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
