To help students learn the appropriate text structures, text features, and language of informative/explanatory writing, teachers might begin with Talk-alouds. Below you will see two 2nd grade examples that focuses on the use of diagrams. These are a paired set of a Reading Talk-aloud and a Writing Talk-aloud.
functional group. n. An atom or group of atoms, such as a carboxyl group, in an organic compound that defines the structure of a family of compounds and determines the properties of the family. functional group. n.
Functional Groups. A. functional group. is a defined grouping of atoms in an organic molecule. A given functional group exhibits a. characteristic set of chemical properties, which are largely independent of the rest of the structure of the molecule in. which it is found.As a consequence, an understanding of the chemical behavior of the functional groups allows one. to predict the reactivity of a wide variety of organic molecules.H 32M/30 28M Functional Groups A functional group is a defined grouping of atoms in an organic molecule.
