Chemicals used for communication in nature are called pheromones. The pheromone used by the female tiger moth to attract the male is the alkane 2-methylheptadecane. Write out its structural formula.

What are the generic structures for carboxylic acids and esters? Write a structure for a specific carboxyl?

Write a balanced chemical equation for the reaction of ethene with oxygen. O a. C2H4(g) + 302(g) → 2CO2(g) + 2H2O(g) O b. 2C2H2(g) + 502(g) → 4CO2(g) + 2H2O(g) O c. CH4(g) + 2O2(g) → CO2(g) + 2H2O(g) O d. C2H4(g) + 202(g) → 2CO2(g) + 2H2(g) O e. 2C2H6(g) + 702(g) →> 4CO2(g) + 6H2O(g)

Is the reaction between an alkene and a halogen a substitution reaction or some other reaction? Explain the reaction mechanism by giving an example.

Write an equation for each of the following reactions. Use molecular and structural formulas and classify the reaction as combustion, addition, substitution, hydro genation, or hydration.

Use the following information to answer the question A student added bromine solution to a hydrocarbon sample that contained an isomer of C6H12 (E) in the absence of light. After shaking the sample, the student noticed that the colour of the bromine solution changed from orange to colourless. 6. An interpretation that could be made from the student's observations is that the hydrocarbon sample is and the IUPAC name of the sample could be ii. I The statement above is completed by the information in row: Row i ii A saturated B saturated hex-2-ene cyclopentane C unsaturated hex-2-ene D unsaturated cyclopentane -12 markel

State whether the statements are true or false. 1. Unsaturated hydrocarbons must contain at least one carbon-carbon double triple bond. 2. Aromatic compounds usualky undergo addition reactions. 3. Carboxylic acid molecules are much less polar than the corresponding alkane molecules. 4. Marikovnikov's rule states that, in an addition reaction involving a hydrogen atom, the hydrogen atom will usually bond to the carbon atom with the fewest hydrogen atoms attached. 5. But-1-ene and 2-ene are structural isomers of each other. 6. Aldehydes contain a carbonyl group on the terminal carbon atom.

Can functional groups be identified in organic compounds by using their chemical and physical properties?

Propane reacts with water to form 2-hydroxypropane. This type of reaction is called substitution  halogenation  hydrohalogenation  hydration

Ketones, aldehydes, carboxylic acids, esters, and amides all have a carbon-oxygen double bond (often called a carbonyl group). Explain how these classifications of organic compounds are different from each other.
