Properties and Reactivities of Common Functional Groups

SAMPLE PROBLEM 15.3 Recognizing the Type of Organic Reaction 

Problem State whether each reaction is an addition, elimination, or substitution (a) CH3—CHa—CHa—Br ---- CH3—CH CHj + HBr 

Plan We determine the type of reaction by looking for any change in the number of atoms bonded to C  

FOLLOW-UP PROBLEM 15.3 Write a balanced equation for each of the following  

In an addition reaction, a tt bond breaks and the two C atoms bond to more atoms. In an elimination reaction, a tt bond forms and the two C atoms bond to fewer atoms. In a substitution reaction, one atom replaces another atom, but the total number of atoms bonded to C does not change.

Some Important Classes of Organic Reactions Properties and Reactivities of Common Functional Groups... 

Although transferability of properties associated with local molecular moieties, for example, the transferability of the expected types of reactions and the degree of reactivities of chemical functional groups, are among the most commonly used assumptions of classical chemistry, nevertheless, within a quantum-mechanical framework, transferability has some natural limitations. 

Functional groups ate specific arrangements of atoms that ate responsible for the properties and reactivity of organic compounds. Common functional groups and their formulas include...
