Is 1-methylpropane a correct way of naming butane?

No, because it IS butane.
1-methylpropane says that:
- Three carbons are in the main chain ("prop-").
- One methyl group (
#"H"_3"C"-# ) is attached to carbon-1 ("1-methyl")
#color(white)(.....)"CH"_3#
#color(white)(a....)|#
#"H"-"C"-"CH"_2-"CH"_3#
#color(white)(a....)|#
#color(white)(aaa)"H"#
But that's the same as simply having four carbons in a row and bonding each of them with the appropriate number of hydrogen atoms.
#"H"_3"C"-"CH"_2-"CH"_2-"CH"_3#
Thus, they are not different isomers (whether they're constitutional, conformational, stereochemical, etc). They are identical compounds.
