Properties of organic compounds are listed as an introduction to this presentation. Topics touched on include the general structure of an alkanes, how to name them, and how to balance related combustion reactions. The presentation is a complete package: informative, practical, and attractive!
In this alkanes worksheet, students use a data table to plot a graph of boiling point against number of carbon atoms. Students define cracking and double bond. This worksheet has 5 short answer questions.
Salman reviews the justifications for naming molecules according to their makeup. He gives a valuable list of traditional prefixes and shows multiple examples of naming alkanes.
Given the line structure or IUPAC name, advanced chemists provide the line structure or chemical name for twenty alkanes. This straightforward assignment can be given as homework during your organic chemistry unit.
Chemistry and earth science meet in a lesson on carbon dioxide emissions. After reading about atmospheric problems caused by using fossil fuels, science stars balance equations for the burning of different alkanes. They compute the number of moles of gasses emitted and consider the use of photovoltaics and other clean energy sources. Although it is only a paper and pencil assignment, it is well-written and pertinent when you want to open your chemists' eyes to the threat of climate change.
Students calculate stoichiometrically the amount of carbon dioxide that would be emitted from burning a mole of varios alkanes that comprise fossile fuels. If the energy released from burning a mole of these alkanes is known, then the amount of carbon dioxide emitted per unit of energy produced can be determined.
Students explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct a model of a simple hydrocarbon molecule using a molecular model kit.
Students collect and analyze data. In this chemistry lesson, students collect data to measure the amount of evaporation that occurs in alkanes and alcohols. Temperature probes are used to help with evaporation.
This instructional activity asks learners to work on alkane nomenclature. They name 2 straight-chain alkanes and answer 4 questions about branched-chain alkanes. In addition, class members name 5 branched-chain alkanes and draw the structures for 3 alkane compounds. This meant for advanced pupils.
In this alkanes learning exercise, students complete a table with the chemical formula, the structural formula and the condensed formula of various alkanes given different numbers of carbon atoms. They answer three questions about valence electrons and Lewis dot formulas as well.
In this bonding worksheet, students write the chemical formula, the name of the alkane, the structural formula and the condensed formula given the number of carbon atoms in each alkane.
In this alkane reactions worksheet, students define combustion, and write the balanced chemical reactions for the combustion of three different alkanes. They also complete six chemical reactions by writing the products.
In this alkanes worksheet, students solve five problems including balancing equations, writing formulas, drawing isomers, drawing line structures and naming compounds.
In this alkanes worksheet, students complete a graphic organizer by filling in the number of carbon atoms for the given alkanes. Students plot a graph showing how physical properties change with the number of carbon atoms. Then students complete 2 short answer questions.
In this alkanes worksheet, students compare the average standard bond enthalpy for common bonds. Then students complete 3 short answer questions.
In this alkane reactions learning exercise, learners define combustion and write the balanced equations for the combustion reactions. Students write the structural formulas of the products including all possible isomers and their percent formation. This learning exercise has 3 problems to solve.
In this chemistry worksheet, students name each of the branched alkanes presented on the sheet. Then they draw the structural formulas for the molecules.
In this alkanes worksheet, students name 12 molecules given the organic structure drawings including the carbon atoms. Students have to identify the name of the compound from the given structure.
Nine action-packed organic chemistry exercises are contained in this mini-unit on carbon containing compounds. Examples include constructing models of alkanes, producing aromatic esters, and preparing pigments for paint and dyes. Chemistry scholars learn to write molecular formulas and draw structures for carbon compounds. Because of the complexity of the activities and level of skills required, this would not be recommended for first-year chemistry classes. It is, however, a superior resource!
High schoolers explore different activities in biology, physics and chemistry. In this science lesson, students examine chromosomes using a microscope and explain their significance in sustaining life on Earth. They investigate alkanes and describe the process of 'cracking' hydrocarbons.
