Organic Chemistry

Homologous Series: An homologous series is a set of compounds whose components differ by a
single repeating functional group. In the case of (straight chain) alkanes, CH2. Their
general formula is CnH2n 2. The chemical properties of the individual members of an
homologous series are similar and they show a gradual change in physical properties.


Hydrocarbons: Compounds containing only hydrogen and carbon. There are three types alkanes, alkenes and alkynes.

A saturated molecule contains single covalent bonds only. An unsaturated molecule contains
one or more multiple (double or triple) covalent bonds.


Isomers are compounds with the same molecular formula but a different arrangement of atoms
in space. Structural Isomerism have the same molecular formula but different molecular
structures, i.e. the atoms are bonded together in a different sequence.


Homolytic fission
The Bond breaks evenly with one electron from the bonding pair going to each atom A° °B
This produces species with single electrons called free radicals. Free radicals are most
commonly formed when the bond being broken has electrons that are fairly equally shared.

    Plastics The Recycling of Thermoset Materials into Thermoplastic Composites Abstract Thermoset process scrap costs companies millions of dollars annually. Specific thermoplastics could benefit from the addition of recycled thermoset material. The incorporation of thermoset regrind into thermoplastic material would provide a viable alternative for the thermoset scrap that is currently sent to the landfills. Theory and Background When a thermoset part has been cross-linked, that material either ha

    Fetal Alcohol Syndrome Many pregnant women are not aware of the complications that are involved with pregnancy. The greater majority of young women see pregnancy as a way of bringing a life into the world but do not use precaution in their dietary habits to prevent the destruction or inhibition of such a life. Most pregnant women continue on their drinking and drug abuse binge right throughout their pregnancy. They do not think ahead to the inexplicable damage that it could do to their fetus. Wh

    Global Markets Building a sustainable competitive advantage is widely viewed as a key factor underlying an effective marketing strategy (Day 1990; Porter 1980). Yet despite the growing importance of international markets and the increasing number of firms expanding internationally, most discussion has been confined to the domestic market. In international markets, interest has primarily been focused on the extent to which domestic market conditions provide industries with an advantage in competi

    Stress3 Stress by Ashley Strawder I. What Is Stress? Stress is the combination of psychological, physiological, and behavioral reactions that people have in response to events that threaten or challenge them. Stress can be good or bad. Sometimes, stress is helpful, providing people with the extra energy or alertness they need. Stress could give a runner the edge he or she needs to persevere in a marathon, for example. This good kind of stress is called eustress. Unfortunately, stress is often no

Crystals have fixed angles between its faces, which have distinct edges. If the faces of a crystal can reflect light, then it will sparkle (Stangle). Crystals have constant angles because of the regular arrangement of its particles. There are seven types of crystals: cubic, tetragonal, orthorhombic, hexagonal, trigonal, monoclinic

  • Lightning and static
    lightning and static Lightning is a discharge of static electricity in the atmosphere, which causes a bright flash of light. When lighting goes through the air, it heats the air to degrees hotter than the sun\'s surface about 50,000 degrees fahrenheit. This heating causes the air to expand and contract. This causes the sound called thunder. Lightning is caused by a build up of negative ions in the atmosphere which discharges into the ground causing the negative ions to go with the positive ions
