Consider the hydrocarbon below. A skeletal model has line segments that slant down, run flat in a double bond, slant up, and run flat. Which of these is a trans- isomer of the above hydrocarbon? A skeletal model with a 6 carbon chain, with a double bond between the second and third carbon. A skeletal model with line segments that slant up, run flat in a double bond, slant down, run flat, and slant down again. A skeletal model of a 5 carbon chain with a double bond between the first and second carbons. A skeletal model with line segments that slant up, fun flat in a double bond, slant up, and run flat.
