The other form is trans-2-butene. The conversion of the cis form to the trans form is slow at room temperature, and the two forms represent two distinct compounds. Conversion of the cis to the trans form involves rotation about the C-C double bond, which requires a substantial amount of energy on the molecular scale. Move the slider to observe the different conformations and their energies along the pathway of the conversion. Consider the linkage between the two central C atoms in cis-2-butene. How many sigma bonds join these two C atoms? Potential Energy 10 J

Alkyl halides can be reduced to alkanes by a radical reaction with tributyltin hydride, (C4H9)3SnH, in the presence of light (hv). Propose a radical chain mechanism by which the reaction might occur. The initiation step is the light-induced homolytic cleavage of the Sn-H bond to yield a tributyltin radical.
