alkanes are hydrocarbons that contain what type of bonds
Most of the compounds in crude oil are hydrocarbons. This means they only contain hydrogen and carbon atoms, joined together by covalent bonds. Remember that a covalent bond is a shared pair of electrons.ydrocarbons are compounds made from carbon and hydrogen atoms joined by covalent bonds. Alkanes are saturated-they have only single bonds. Alkenes have a double bond-they are unsaturated. Alkenes react with brown bromine water and decolourise it, but alkanes do not. Alkenes can act as monomers.
