Structural isomers are compounds with the same atoms, but different chemical bonds.
00:07
That is, they have the same chemical formulas, but different arrangement of atoms.
00:13
So, smallest alkan that has a structural isomer is butane, and its chemical formula is c4h10.
00:31
And butane could be represented as a straight chain alkan or a branched chain alkyne.
00:55
So as a straight chain alkin, we have four carbon atoms in a one chain and we will have 10 hydrogen atoms.

1, 2, 3, 4, 5, 6, 7, 8, 9.

Okay? so this is a straight chain...
