Write the structures of alkenes, ethene and propene. What are they called?(1) Draw the structures of (1) diamond (ii) graphite.(c) What are hydrocarbons ? Write the structures of hydrocarbons with two carbon atomscontaining (1) carbon-carbon single bond (in) carbon-carbon double bond (ii) carbon carbontriple bond.​

Answer»

Answer:

As noted before, alkenes are HYDROCARBONS with carbon-to-carbon DOUBLE bonds (R2C=CR2) and alkynes are hydrocarbons with carbon-to-carbon triple bonds (R–C≡C–R). Collectively, they are called unsaturated hydrocarbons because they have fewer hydrogen ATOMS than does an alkane with the same number of carbon atoms, as is indicated in the following GENERAL FORMULAS
