To switch two substituents on carbon atoms, first click the button below to turn the feature on, and then click on any carbon atom.

<jmol><jmolbutton><text>switch substituents</text><script>set picking invertstereo</script></jmolbutton></jmol>

<jmol><jmolbutton><text>make skeletal</text><script>select all; label "%e";set labelOffset 0 0; color label black;delay 1.0;

select _C; select within(1.1, selected); spacefill off; delay 1.0; select selected and _H; hide selected</script></jmolbutton></jmol>

For each molecule, write the skeletal structure, figure out the name, and explore whether it is different from its mirror image (whether it is chiral). For the last question, it helps to figure out whether any of the carbon atoms have four distinct groups connected to it.
