The vector stencils library 'Chemical drawings' contains 81 symbols of organic compounds and functional groups for chemical drawing.
Use it to draw structural formulas of organic molecules, schemes of chemical reactions and organic chemistry diagrams.
'Structural drawings.
Organic molecules are described more commonly by drawings or structural formulas, combinations of drawings and chemical symbols. The line-angle formula is simple and unambiguous. In this system, the endpoints and intersections of each line represent one carbon, and hydrogen atoms can either be notated explicitly or assumed to be present as implied by tetravalent carbon. The depiction of organic compounds with drawings is greatly simplified by the fact that carbon in almost all organic compounds has four bonds, nitrogen three, oxygen two, and hydrogen one. ...
Organic reactions.
Organic reactions are chemical reactions involving organic compounds. While pure hydrocarbons undergo certain limited classes of reactions, many more reactions which organic compounds undergo are largely determined by functional groups. The general theory of these reactions involves careful analysis of such properties as the electron affinity of key atoms, bond strengths and steric hindrance. These issues can determine the relative stability of short-lived reactive intermediates, which usually directly determine the path of the reaction.
The basic reaction types are: addition reactions, elimination reactions, substitution reactions, pericyclic reactions, rearrangement reactions and redox reactions. ...
Each reaction has a stepwise reaction mechanism that explains how it happens in sequence - although the detailed description of steps is not always clear from a list of reactants alone.
The stepwise course of any given reaction mechanism can be represented using arrow pushing techniques in which curved arrows are used to track the movement of electrons as starting materials transition through intermediates to final products.' [Organic chemistry. Wikipedia]

Basic Electrical And Electronic Symbols
- Note: The schematics symbols for most major electrical components can be found in this table. However, each component may have numerous possible representations. In cases where there is more than one common symbol we have tried to give an alternate representation. COMPONENT SYMBOL ALTERNATE Ammeter And Gate Antenna, Balanced Antenna, General.
- Value in terms of the decimal submultiple (10–3) of a unit (ampere) of current; mA is the unit symbol for milliampere. Other symbols (such as j, exp, Cu) are used to indicate mathematical operations, chemical elements etc. Frequently occurring technical phrases are.

Basic Electrical Symbols
Architectural Blueprint Symbols. Here is a list of all the blueprint symbols that are needed to make architectural, electrical and plumbing blueprints. Because of the scale, many of these symbols are hard to see on real blueprints. The electrical floor plan map below shows some of the symbols used by electricians. The electrical and electronic symbols shown here are those that are likely to be encountered by the aviation maintenance technician. They are in accor-dance with ANSI-Y32.2-1975. Only those symbols associated with aircraft electrical and elec-tronic wiring have been listed in general. R e-fer to ANSI-Y32.2-1975 for more.
