So because two is the smallest, it traveled greatest along this vertical direction. Four is this segment here. And because four is slightly smaller than one, it travels farther than one. But notice what happened to three, because three, after we exposed the two performic acid has been separated because these two bonds broke. Three now consists of three A and three B that are not connected. And so when we run gelature freezes along the vertical direction, what happens is they will actually separate because three A is much smaller than three B.
