CHM 1430 Study Guide - Final Guide: Structural Formula, Trigonal Pyramidal Molecular Geometry, Lewis Structure
Document Summary
Diagram of an atom, ion or molecule in which each dot represents a valence electron condensed structural formula structural molecular formula showing the general arrangement of atoms but without showing all the covalent bonds. Helps represent that actual 3d shape of a molecule on a flat piece of paper. Wedge: (triangle) show an atom is coming towards you. Dash: (dotted line) show an atom is going away from you. -note: wedge and dash notation is only used in tetrahedral, trigonal pyramidal, & octahedral geometries skeletal notation hydroxyl group. An oxygen bonded to a hydrogen carbonyl group. A nitrogen singly bonded to two hydrogens or carbons, or one of each amine group. A carbon singly bonded to an amino group. A carbonyl carbon bonded to an amino group biomolecules. Carbohydrates polymers made from sugars; class of biochemical referred to as simple or complex sugars. Amylose and amylopectin plant starches (x and x)
