Proposed a detail mechanism for the zinc mediated debromination of trans-1,2-dibromocyclohexane. The reagent used was zinc and water and heat where also added to the reaction. The products fromed included ZnBr2 and cyclohexane
Indicate all atomic orbitals and molecular orbitals as well as molecular orbitals for both the core and valence electrons. Fill your MO in part b with the appropriate number of electrons.
Carbon disulfide, CS2, is a volatile, flammable liquid. It has a vapor pressure of 400.0 mmHg at 28.0°C and 760.0 mmHg at 46.5°C. What is the heat of vaporization of this substance?
Restricting yourself to straight-chain (unbranched) compounds, draw the structures of the possible constitutional isomers of pentene. There are two "variables" -- the position of the double bond; and cis/trans isomerization at that double bond.
