1-Pentanol can be made via two different Grignard reactions: one using a one-carbon oxygen-containing compound and the other from a two-carbon oxygen-containing compound. Provide the retrosynthetic analysis for both routes by drawing the requested combination of Grignard reagent and organic compound. For the Grignard reagents, use bromine as the halogen.

When a nucleus absorbs a neutron and then breaks apart, there are many products of the reaction. what is not a product of a nuclear fission reaction

What is a possible quantum number set for an electron in the 3s orbital of a magnesium atom

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
