Aromatic hydrocarbons need to be explained by taking example of benzene. The difference between delocalization of electrons in benzene and in simple alkenes and alkynes needs to be explained. Concept introduction: Aromatic hydrocarbons are known by the presence of sigma bond and delocalized pi electrons between the carbon atoms which are in cyclic form. Benzene, toluene, anthracene etc. are some common aromatic hydrocarbons.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
