Verified step by step guidance
1
Identify the longest continuous carbon chain in the given structure. The structure shows a straight chain of 5 carbon atoms connected sequentially.
Count the number of carbon atoms in this longest chain. Here, the chain has 5 carbon atoms.
Recall the IUPAC names for straight-chain alkanes based on the number of carbons: 1 carbon is methane, 2 is ethane, 3 is propane, 4 is butane, and 5 is pentane.
Since the chain has 5 carbons and no branches or functional groups, the compound is a straight-chain alkane named pentane.
Confirm that no substituents or functional groups are present that would alter the base name or require additional prefixes or suffixes.
