Concept introduction:
The structural formula of a compound represents the molecular structure along with the atom connectivity and bonding arrangement.
Alkene contains a double bond between two carbons atoms whereas
Due to the presence of a double bond, the rotation about adjacent carbon-carbon atoms is highly restricted. Hence, alkenes can exist in two forms which have the similar molecular formula but different types of arrangement of atoms around the double bond. This isomerism is a type of stereoisomerism which is known as geometric isomerism or cis-trans isomerism, for example, 1, 2-dichloroethane can show the geometrical isomerism,

- Write the molecular formula of each alkane.arrow_forwardGasohol is a mixture of 90% gasoline and 10% ethanol, CH 3CH 2OH. Ethanol is considered an environmentally friendly fuel additive because it can be made from a renewable source—sugarcane. Ethanol burns in air to form CO 2 and H 2O, and, like the combustion of alkanes, this reaction also releases a great deal of energy. Write a balanced equation for the combustion of ethanol.arrow_forward1. The chemical formula C4H100 results in four alcohols and three ethers for a total of seven structural isomers. Draw pairs of structural formulas for these molecules that illustrate positional and functional isomerism on a sheet of paper. You will be drawing a total of four formulas. Label each pair as positional or functional.arrow_forward
- Write the structural formula for propylene glycol, 1,2-propanediol. Why is it classified as an alcohol? Is it a polar molecule? Should it be miscible with water?arrow_forwardDraw the skeletal structure of these alcohols isobutanol, 1-butanol, isopentanol, benzyl alcoholarrow_forwardWrite structures of different isomers formed by C6H10. Also write IUPAC names of the all the isomers.arrow_forward
- What is the condensed structural formula of Al4C3+12H2O -> 4Al(OH)3 +3CH4arrow_forward3) Give the structural formulas and the old and new IUPAC names of all eight open-chain isomeric alcohols with the molecular formula CSH11OH. Indicate which of these isomers are primary, secondary, or tertiary alcohol. 4) Six isomeric saturated ethers have the molecular formula CsH120. Write the structural formula and name for each of these ethers.arrow_forwardName this compound: H₂C-CH₂-C=CH₂ CH₂ Name an isomer of this compound that has the following structure:arrow_forward
- What is cis-trans isomerism in alkenes? cis-trans isomerism in alkenes involves having the major groups in an alkene on the same or opposite side of the double bond cis-trans isomerism in alkenes involves having different or identical substituents at the both ends of the double bond cis-trans isomerism in alkenes involves having the major groups in an alkene in staggered or eclipsed conformations cis-trans isomerism in alkenes involves different location of double bond along the carbon chainarrow_forwardWhat is cis-trans isomerism in alkenes? cis-trans isomerism in alkenes involves having the major groups in an alkene on the same or opposite side of the double bond cis-trans isomerism in alkenes involves having different or identical substituents at the both ends of the double bond cis-trans isomerism in alkenes involves having the major groups in an alkene in staggered or eclipsed conformations cis-trans isomerism in alkenes involves different location of double bond along the carbon chain How do the properties of cis-trans isomers differ from one another? cis and trans isomers have identical physical properites, whereas their chemical properties differ cis and trans isomers have identical chemical properites, whereas their physical properties differ cis and trans isomers have identical physical and chemical properties cis and trans isomers have distinct physical and chemical propertiesarrow_forwardNote the number of isomers for Butane and Octane. Why does the number of possible isomers go up with an increasing number of carbon atoms?arrow_forward
