Introduction

Reduction reactions are very important in chemistry as they are effective processes for synthesizing new compounds from existing ones. In organic chemistry, a compound is said to be reduced if it acquires new hydrogen. There are diverse reagents for carrying our reduction reactions. Two of these are sodium borohydride (NaBH4) and lithium aluminum hydride (LiAlH4) - the latter is a more powerful reducing agent compared to the former. In this experiment, NaBH4 was used to reduce p-Nitrobenzaldehyde to form p-Nitrobenzyl alcohol. NaBH4was used over LiAlH4 in this experiment, because LiAlH4 would also reduce the nitro group of the aldehyde.

Article 1: The case for minimizing risk in your bond holdings by William Bernstein

There is always a trade-off between risk and return. Investors are rational and risk-averse hence, they require additional returns when the risk involved in any investment is high. In this article, William Bernstein explains how investors can reduce the risk in their investments in bonds without necessarily interfering with the expected returns on the bonds. One of the risks affecting bondholders is the interest risk. Changes in interest rates affect the return on bonds. When interest rates rise, bondholders lose since the prices of bonds fall. This is because the bond will be paying a lower coupon interest compared ...
