Which of the following is the correct IUPAC name for the compound with the molecular formula C4H10?
A
Butane
B
Propane
C
Hexane
D
Pentane
Verified step by step guidance1
Step 1: Understand the molecular formula C4H10. This formula indicates that the compound consists of 4 carbon atoms and 10 hydrogen atoms.
Step 2: Recall the IUPAC naming convention for alkanes, which is based on the number of carbon atoms in the longest continuous chain. The prefix 'meth-' is for 1 carbon, 'eth-' for 2 carbons, 'prop-' for 3 carbons, 'but-' for 4 carbons, and so on.
Step 3: Identify the correct prefix for 4 carbon atoms, which is 'but-'. This prefix is used for alkanes with a straight chain of 4 carbon atoms.
Step 4: Combine the prefix with the suffix '-ane', which is used for saturated hydrocarbons (alkanes). Therefore, the name for a straight-chain alkane with 4 carbon atoms is 'butane'.
Step 5: Verify that the name 'butane' matches the molecular formula C4H10, ensuring that it is the correct IUPAC name for the compound.
