Structural Isomers – Just how many structures can you make
Structural Isomers – Just how many structures can you make from a simple formula? 1 methane: CH4 C H H H H CH4 C H H condensed formula 2D formula 3D formula methane 2 ethane: C2H6 Once the two carbons are connected, there are only six additional bonding sites and these are filled by the six hydrogen atoms Ethane is a saturated molecule
C he m g ui d e – que s t i on s STRUCTURAL ISOMERISM
1 There are five structural isomers for hexane, C 6H 14 Draw the five structures using simplified structural formulae For example, one of the isomers of butane, C 4H 10, could be drawn as CH 3CH 2CH 2CH 3 Use the same sort of format for the other questions on this page 2 Draw as many structural isomers as possible for C 3H 8O 3
