Verified step by step guidance1
Identify the structure of 2-bromo-pentanal: It is an aldehyde with a five-carbon chain (pentanal) and a bromine atom attached to the second carbon.
Look for the aldehyde group (C=O) at the end of the carbon chain, which is characteristic of an aldehyde.
Count the carbon atoms in the chain to ensure there are five, which corresponds to 'pentanal'.
Locate the bromine atom on the second carbon of the chain, which is indicated by '2-bromo'.
Compare each provided structure to these criteria to determine which one matches the description of 2-bromo-pentanal.
