Answer
Same molecular formula but different structural arrangements
Explanation
Structural isomers have the same molecular formula but differ in the arrangement of atoms. This is a key concept in organic chemistry, highlighting how different structures can lead to different properties.
Common mistake
Incorrect Naming of Organic Compounds
Students often confuse the naming of branched alkanes, leading to incorrect IUPAC names.
To correctly name branched alkanes, identify the longest carbon chain as the parent chain, number the chain to give the substituents the lowest possible numbers, and use prefixes for the substituents. For example, for 2-methylpentane, the longest chain is pentane with a methyl group on the second carbon.
