Abstract This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration. The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction‚ in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a suitable electrophilic reagent‚ and many other groups besides nitro may be introduced into the ring. Although the reaction produced a low

Unsaturated Hydrocarbons Unsaturated hydrocarbons Have fewer hydrogen atoms attached to the carbon chain than alkanes. Are alkenes with double bonds. Are alkynes with triple bonds. 1 Structure of Alkenes Alkenes (and alkynes) are unsaturated hydrocarbons Alkenes have one or more double bonds The two bonds in a double bond are different: - one bond is a sigma () bond; these are cylindrical in shape and are very strong - the other is a pi (π) bond; these involve sideways overlap of

Department of Biological Sciences - College of Science‚ University of Santo Tomas‚ Manila ABSTRACT The unknown hydrocarbon sample was differentiated and characterized by the use of three tests. The outcomes of these tests are as follows: Nitration test (negative)‚ Bromine test (positive) and Basic Oxidation test (positive). From these results the unknown sample can be classified as non-aromatic and unsaturated. INTRODUCTION Hydrocarbons are organic compounds that consist of only C and

2-(2‚4-Dinitrobenzyl) pyridine Peter Defnet and Cody Krepps Department of Chemstry Juniata College Huntingdon‚ PA September 18‚ 2012 Abstract: Nitration of 2-benzylpyridine is supposed to yield 2-(2‚4-Dinitrobenzyl) pyridine‚ when electrophilic aromatic substitution is the mechanism. Experiencing many pitfalls‚ however‚ has lead to the actual product obtained to contain the expected product‚ as well as many impurities. This report examines the supposed mechanism for the electrophilic substitution
