Based on the image description and the options provided, the correct IUPAC name for the given structure is C. 2-methylbutane. Here’s why:
Main Chain Selection: The longest continuous chain of carbon atoms is selected as the main chain. In this case, it’s a butane molecule with four carbon atoms.
Branch Identification: There is a methyl group (CH3) attached to the second carbon of the main chain.
Numbering the Chain: The chain is numbered from the end nearest to the branch. Hence, the methyl group is on the second carbon.
Naming: Combining the above, the IUPAC name is 2-methylbutane, which corresponds to option C.
just writing nonsense up and down myschool. The anwer is D
1dimethylpropane
one amongst those 2 up and down methyls are the the the 2nd carbon atom in the chain, the bent the for a reason 😉
