Experiment 5- Competing Nucleophiles Table of results: Area (mm²) Percent composition 1-bromobutane 511 85.02% 1-chlorobutane 90 14.98% 2-bromobutane 432.25 78.63% 2-chlorobutane 117.5 21.37% 2-bromo-2-methylpropane 280 37.58% 2-chloro-2-methylpropane 465 62.42% Discussion: 1. In 1-butanol Base on the data table‚ 1-bromobutane dominated the composition of 85.02%‚ which indicates the conclusion that the mechanism for 1-butanol is SN2‚ and bromide is a better nucleophile

the ocean‚ the biosphere does not end where light ceases as gravity enables the energy flow to continue downward‚ since fecal pellets‚ cast skins and organisms dead and alive are always falling from the illuminated regions into the depths. In addition to the extension of the biosphere downwards‚ there is a limited extension upwards also. On very high mountains‚ like Himalayas‚ the limit above which chlorophyll-bearing plants cannot live appears to be about 6‚200 meters. In simple words‚ biosphere

Diliman‚ Quezon City 1101 Philippines Date Performed: April 25‚ 2013; Date Submitted: April 30‚ 2013 Alkyl halides could be synthesized through several processes and using different compounds as reactants. One of the simplest method used is the addition of a hydrogen halide to an alcohol. In this research‚ tert-butyl alcohol was reacted with cold concentrated HCl to produce tert-butyl chloride. The crude product was distilled to yield a pure tert-butyl chloride. The tert-butyl alcohol‚ together

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

INORGANIC CHEMISTRY 1 Lab Report on Oxidation & Reduction I. Metal-Metal Ion Displacement II. Halogen Displacement Reactions INTRODUCTION A series of experiments had been conducted to determine the order of displacement strengths of the metals and halogen chosen for the experiments. A displacement reaction is a reaction in which one element(metal or non-metal) displaces another element(metal or non-metal) from its salt solution. In the displacement reaction of metals‚ the more
