1. (a) Alkanes are saturated hydrocarbons.explain the words saturated and hydrocarbons. (b) Alkanes are generally unreactive. Explain why this is so. (c) write balanced equations for the complete combustion of: (i) methane (ii) ethane. 2. Use the passage below and your knowledge to answer the questions that follow. Methane reacts with bromine to give bromomethane and hydrogen bromide. The mechanism for the reaction is called free-radical substitution and involves

REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand

Properties and Reactions of Hydrocarbons Abstract Introduction Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar solvents will dissolve

Experiment #1 – Aromatic Nitration The purpose of this lab is to convert toluene to nitrotoluene through the process of aromatic nitration. This is done by electrophilic aromatic substitution. The aromatic organic compound‚ toluene‚ is reacted under mild conditions with an electrophile‚ the nitronium ion‚ resulting in a product of nitrotoluene. Failure to use mild conditions may result in polynitration. Different reaction conditions were studied to understand the effect of nitrating agent

Analysis of Hydrocarbons Myra Gurango‚ Geneva Guy‚ Micah Hernandez* and Joyce Lagarde Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract The organic compounds hexane‚ toluene‚ cyclohexene and naphthalene in hexene were subjected to parallel chemical testing to differentiate their intrinsic physical properties in terms of structure and behavior. The physical state and color were noted by simple physical observation. Nitration Testing was conducted for preliminary

Classification Tests for Hydrocarbons Authors: Goldie Ann Tejada‚ Allain Joseph S. Templo‚ Kristinlyn Trajano‚ Kevin Viray‚ Quennie Yu Group 10‚ 2F-PH‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT The test compounds undergo different physical and chemical tests to differentiate their intrinsic physical properties and chemical properties. Physical state‚ color‚ and odor were noted through simple observation. Miscibility of the test compounds were noted through color change or a warming

What is hydrocarbon? A compound of hydrogen and carbon‚ such as any of those that are the chief components of petroleum and natural gas OR Organic compound (such as benzene‚ methane‚ paraffin) made of two elements carbon and hydrogen and found in coal‚ crude oil‚ natural gas‚ and plant life. Hydrocarbons are used as fuels solvents‚ and as raw materials for numerous products such as dyes‚ pesticides‚ and plastics; petroleum is a mixture of several hydrocarbons
