Abstract The aliphatic and aromatic hydrocarbon are can be differentiate by .For example‚in the experiment involving aliphatic hydrocarbon which is cyclohexane that undergo the reaction with bromine water in the presence of UV light.This reaction is known as substitution reaction.The cyclohexane that react with bromine under present of UV light will change to slightly brown while the other one has no changeous which is still brown.For baeyer’s test‚the alkane which is heptanes will not undergo the

Nucleophilic Substitution Samantha Gutierrez Nucleophilic Substitution Introduction: The purpose of this lab is to investigate how different factors affect the rate of SN1 and SN2 reactions. SN2 reactions proceed via a one step mechanism in which the incoming nucleophile attacks the electrophilic carbon center from the opposite side of the leaving group. This reaction mechanism implies that the stereochemistry of a chiral center will be inverted. SN1 reactions proceed via two steps‚ slow

Import Substitution Industrialization (ISI) Definition Government strategy that emphasizes replacement of some agricultural or industrial imports to encourage local production for local consumption‚ rather than producing for export markets. Import substitutes are meant to generate employment‚ reduce foreign exchange demand‚ stimulate innovation‚ and make the country self-reliant in critical areas such as food‚ defense‚ and advanced technology.

Lab Report: Nucleophilic substitution reaction Introduction: Alkyl halides undergo many reactions in which a nucleophile displaces the halogen atom bonded to the central carbon of the molecule. The displaced halogen atom becomes a halide ion. | | | | Some typical nucleophiles are the hydroxy group (−OH)‚ the alkoxy group (RO−)‚ and the cyanide ion (−C N). Reaction of these nucleophiles with an alkyl halide (R—X) gives the following reactions and products: | | | |

Substitution Reactions* INTRODUCTION In class‚ we have been learning about substitution reactions and the various mechanisms by which they can occur. In a substitution reaction‚ a leaving group‚ usually a halide‚ is replaced by a nucleophile. Two mechanisms have been described for this reaction‚ a unimolecular (SN1) mechanism‚ and a bimolecular (SN2) mechanism. The stepwise unimolecular mechanism proceeds through a carbocation intermediate. These reactions are favored by the use of a substrate

Nomenclature of Aromatic Compounds Aromatic Compounds- possess a ring shaped structure Benzene (C6H6)- aka. naphtha - unsaturated cyclic compound - simplest aromatic HC - all C to C bonds are identical; each C has a H atom - substitution reactions occur instead of addition reaction - delocalized pi bonding in benzene imparts stability (aromaticity); responsible for resistance to addition reactions (involve breaking delocalized bonding) Benzene Derivatives- produced when one or more H atoms on benzene
