Both are butane. which have
Isomers are compounds with the same molecular formulae but different structural formulae. 38 The Production of Polyethylene. Information about naming esters is included in some school chemistry courses, such as UK A-Level … I and III. Another example of isomerism occurs in phenethylamine drugs. Most alkanes you will come across are relatively small molecules in which all the chemical bonds are covalent bonds. 988860 Hi all, Can someone explain why this is called E-3-methylpentane Thanks very much in advance. . the same molecular formula
The name of the molecule can be changed to reflect this, but we’ll save the naming of molecules for another post. 2. Please remember, when you are naming an isomer.
