The name 2-butylpropane is incorrect for a branched alkane, but the correct name can be deduced from it. What is it?
A) 1-methylhexane
B) 1-methypentane
C) 2-methylhexane
D) 2-pentylmethane
Branched Alkane
A type of alkane hydrocarbon with a tree-like structure, as opposed to linear alkanes, which improves fuel quality in terms of octane rating.

Final Answer :
C
Explanation :
The correct name deduced from "2-butylpropane" suggests a butyl group (4 carbons) attached to a propane molecule (3 carbons) at the second carbon. This configuration actually describes a straight-chain alkane with a total of 7 carbons, where one of the carbons in the main chain is bonded to an extra methyl group (1 carbon), making it 2-methylhexane.
