ALKENES ( 2 nd ) Dr. Marwa Eid 1. Alkenes – unsaturated hydrocarbons (C n H 2n ) reactivity: the double bond is responsible for their reactivity 1.
REACTIONS OF HYDROCARBONS REACTIONS OF ALKANES the single covalent bonds between carbon atoms in saturated and unsaturated hydrocarbons are difficult to.
Alkenes E The double bond consists of a bond and a bond bond from head-on overlap of sp 2 orbitals bond from side-on overlap of p orbitals bond.
Reactions of Unsaturated Hydrocarbons Combustion Complete combustion C 3 H 6 + O 2 → CO 2 + H 2 O Incomplete combustion C 3 H 6 + O 2 → C + CO + CO 2.
