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

CHAPTER 21 ORGANIC CHEMISTRY - UC Santa Barbara
Isomers are distinctly different substances Resonance is the use of more than one Lewis structure to describe the bonding in a single compound Resonance structures are not isomers Structural isomers: Same formula but different bonding, either in the kinds of bonds present or in the way in which the bonds connect atoms to each other
(2) - Weebly
€€€€€€€€€ Each of the parts (a) to (e) below concerns a different pair of isomers Draw one possible structure for each of the species A to J, using Table 2 on the Data Sheet where€appropriate (a)€€€€ Compounds A and B have the molecular formula C5H10 A decolourises bromine water but B does not A
Aldehydes and ketones - StFX
• Positional isomers are possible for ketones (but not aldehydes) • And skeletal isomers are possible for both 3-Pentanone C 5 H 10 O 2-Pentanone C 5 H 10 O 2-Pentanone 3-Methyl-2-butanone Positional isomers: functional group is in different positions on same carbon skeleton Skeletal isomers: have different carbon skeletons
The following five isomers, P Q R S and T using nmr
This question concerns isomers of C6H12O2 and how they can be distinguished using n m r spectroscopy (a) €€€€The non-toxic, inert substance TMS is used as a standard in recording both 1 H and 13 C
