Benzil Reduction Introduction The objective of the experiment was to reduce Benzil‚ using sodium borohyride as the reducing agent. In a benzil reduction‚ there are five possible products than can occur‚ specifically a racemic mixture of benzoin‚ racemic mixture of hydrobenzoin‚ or meso-hydrobenzoin. Therefore‚ three different tests were conducted in determining the identity of the product: melting point‚ thin light chromatography‚ and infrared spectroscopy. (a) Mechanism and reaction equation

The Balmer series is characterized by the electron transitioning from n ¡Ý 3 to n = 2‚ where n refers to the radial quantum number or principal quantum number of the electron. The transitions are named sequentially by Greek letter: n = 3 to n = 2 is called H-¦Á‚ 4 to 2 is H-¦Â‚ 5 to 2 is H-¦Ã‚ and 6 to 2 is H-¦Ä. As the spectral lines associated with this series are located in the visible part of the electromagnetic spectrum‚ these lines are historically referred to as H-alpha‚ H-beta‚ H-gamma and

Solution: Apply integral test: Z Z ln R 1 X R 2 1 p dx x (ln x) p=1 p 6= 1 let ln (x) = u then ln 2 so that when p = 1 and p < 1 integral diverges by letting R ! 1‚ so does the series. When p > 1 then integral converges to ! 1 p 1 p 1 p (ln R) (ln 2) (ln 2) lim = ‚ R!1 1 p 1 p 1 p so does the series. 2. (18 pts.)
