dipole. 6 Structure and Properties of Alcohols •Alcohols have an H atom bonded to an O atom‚ making them capable of intermolecular hydrogen bonding. •All of these properties give alcohols much stronger intermolecular forces than alkanes and alkenes. 7 Structure and Properties of Alcohols •Therefore‚ alcohols have higher boiling and melting points than hydrocarbons of comparable size and shape. stronger intermolecular forces higher boiling and melting point 8 Structure and

fractions from the refining of petroleum Catalytic cracking is the process whereby high molecular weight fractions are broken down to low molecular weight ones. This process is used in petroleum refineries where crude oil is broken down to smaller alkenes and alkanes‚ until ethene‚ propene‚ (or both) are formed. Catalytic Cracking allows greater output of high-demand products. Identify that ethylene‚ because of the high reactivity of its double bond‚ is readily transformed into many useful products Ethylene
