Consider the structure of the phosphonium ylide formed by treatment of the following haloalkane with triphenylphosphine followed by butyllithium. draw the structure of the alkene formed by reaction of this phosphonium ylide with acetone.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.

If you need to add 27.50ml of a solution, which piece of glassware would you use to deliver this volume and explain how you would determine if the 27.50 ml was measured?
