to see or realize that where n how we having our life much easier than it used to be. In these writing assignments‚ the topic is about the organic chemistry. In organic chemistry‚ we all have different kinds of compounds. In addition‚ alkanes‚ alkenes‚ and alkynes are the parts of the organic and inorganic compounds. We also can learn about the structural formula they all have in different form. Polymerization is another type of chemical reaction that we get to know. There is also a difference between

Use this packet and your book to answer the questions throughout this packet. Organic Nomenclature - Alkanes‚ Alkenes‚ Alkynes Naming organic compounds can be a challenge to any chemist at any level. Historically‚ chemists developed names for new compounds without any systematic guidelines. In this century‚ the need for standardization was recognized. For simple molecules‚ the nomenclature system worked out by the International Union of Pure and Applied Chemists (IUPAC) works well. For complex

napthalene and toulene were given to serve as reference standards to characterize and distinguish four unknown given samples. Nitration‚ bromine and basic oxidation testswere conducted to classify the different samples from being an aliphatic‚ or aromatic‚ saturated or unsaturated and alkylated or non-alkylated hydrocarbons. The physical state and color were noted by simple physical observation. The unknown samples were characterized and differentiated by using the three different tests to distinguish

Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4. Valence electrons: 4 Property: Non-metal Abundance:- Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon:- The Covalent

Test Bromine addition Alkane Mixture of hexane and dichloromethane was originally clear liquid. After adding 3 drops red color Br2/CH2Cl 2 the solution turned orange. Orange color held. Alkene Alkene used was pentene. Originally clear liquid. After addition‚ solution turned yellowish at first but then turned clear after a few minutes of sitting. Alkyne Alkyne used was toluene. Originally clear liquid. After addition‚ solution turned orange. Orange maintained longer than alkene but eventually turned

Explain the use of crude oil as a source of both aliphatic and aromatic hydrocarbons Crude oil: a complex mixture of hydrocarbons found in layers of rock beneath the earth’s surface Aliphatic Hydrocarbons: contain chains of carbon atoms that may be branched Aromatic Hydrocarbons: contain Benzene rings- rings of carbon atoms with delocalized electrons Alkanes all have different boiling points dependent on the length of the carbon chain in the molecule. The smaller chains ie. the most volatile
