Final answer:
The question asks for the skeletal structures of two molecules with the formula C5H12. Examples include n-pentane with a straight chain and 2-methylbutane with a branched chain structure.
Step-by-step explanation:
The subject of the question involves drawing the skeletal structures of two different organic molecules that each consist of 5 carbon atoms and 12 hydrogen atoms. There are numerous possibilities for such structures, but here we'll consider two examples consistent with the general formula C5H12, typically known as pentanes.
First structure: n-pentane, which is a straight chain alkane with all single bonds and no branches. The skeletal structure is simply a straight line with four bends, each representing a carbon atom at the end or bend, with an additional carbon atom at one of the termini (as every line or bond denotes a carbon to carbon connection).
Second structure: 2-methylbutane (also known as isopentane), which is a branched alkane. The skeletal structure looks like a 'T,' with the vertical line representing three carbons in a straight chain and the horizontal line (at the second carbon from the top) representing a methyl group attached to the middle carbon atom.
