Give all isomers |
|
Answer» \tMethoxyethane and Propanol :The chemical structure, C3H8O exists as several isomers of propanol, as well as the isomer methoxyethane. The two propanol isomers consist of propan-1-ol and propan-2-ol (also known as isopropyl alcohol)\tMethylacetylene and Allene :Methylacetylene and allene are an example of C3H4 isomers, which differ based on the type of bonding exhibited by the molecules. Methylacetylene has one triple bond and one single bond between the carbon atoms and allene exhibits two double bonds between the carbons.\tFulminate and Cyanate :Fulminate and cyanate are an example of isomers of CNO. Fulminate exhibits an arrangement in which the N is bound to both the C and O atoms, whereas in cyanate, both the O and N are bound to the central C atom.\tGlucose and Fructose :Glucose and fructose are an example of C6H12O6 isomers, which differ based on the position of a double bonded O atom. In glucose, the O is situated on the first C, whereas it is located on the second C in fructose (the structures of each are shown below).\tD-Glucose vs. D-Fructose: Structural Formulae Pharmaceutical Examples Isomers are extremely important in the development of pharmaceuticals, as typically, only one isomer of a particular molecule will exert the desired effect. For example, only one isomer for ibuprofen will bind to the necessary target in the human body and induce pain relief. propanols and methoxyethaneA simple example of isomerism is given by propanol: It has the formula C3H8O (or C3H7OH) and occurs as two isomers: propan-1-ol (n-propyl alcohol; I) and propan-2-ol (isopropyl alcohol; II)isomers of propanolExample: propadiene and propyne\tEditPropadiene (or allene) and propyne (or methylacetylene) are examples of isomers containing different bond types. Propadiene contains two double bonds, whereas propyne contains one triple bond. |
