They are all colourless and odourless with the exception of acetylene which has slightly garlic odour due to the presence of PH3 and H2S as impurities. According to experimental evidences, electrophilic substitution reaction involve following three steps: (a) Generation of electrophilic Alkene show both structural isomerism and geometrical isomerism. Aromatic hydrocarbons are immiscible with water but readily miscible with organic solvents. More is the steric crowding, the less is the Boiling point of alkanes decreases on branching. Singh. It is a chain reaction. TEL (tetraethyl lead) is used as antiknocking compound. (x) Corey-Bouse synthesis This method can be used to prepare alkanes having odd number of carbon atoms. Alkynes also exhibit electrophilic addition reaction but less reactive than alkenes because the dissociation of x-electron cloud requires more energy. Forgot 4.
