5.2: Organic Chemistry II One or more of the hydrogen atoms of a hydrocarbon can be replaced by another atom or group of atoms thus forming the other families of organic compounds. These organic families are much more reactive than the hydrocarbons, and the non-hydrocarbon portion of the molecule is called the functional group since it largely determines how the molecule behaves (functions). Replacement of one or more hydrogens of a hydrocarbon by a halogen atom (-F, -Cl, -Br or –I) resu...

What are the differences between aliphatic (including alkanes, alkenes,alkynes and cyclic compounds) aromatic hydrocarbons are. - ALIPHATIC Hydrocarbon: Non-aromatic -Alkanes & CycloAlkanes:single bonds; saturated:Contain only carbon and hydrogen & C-C & C-H single bonds -Alkenes:double bond(s) -Alkynes: triple bond(s) *alkenes and alkynes are unsaturated: at least one C-C double or triple bond(s) AROMATIC Hydrocarbon: benzene ring What is the trend in solubility and boiling point/mel...
