you have to select the longest chain possible yani ke aapne C2H5 ko CH2-CH3 ke form mai likhna hoga phir chain select kren gi

Why "2-Ethylpropane" is IncorrectIt is a common mistake to look at CH₃-CH-CH₃ as the main 3-carbon chain (propane) and treat the C₂H₅ as an ethyl branch. However, IUPAC rules strictly require you to pick the absolute longest continuous chain possible. Because the ethyl group adds more carbons to the path, it changes the main chain from propane to butane.
