Chemistry Exam Study Sheet Organic Chemistry • Study of compounds to which carbon is the principal element. • Carbon is special because it has 4 bonds. Functional Groups • Organic substances are organized into organic families. • Organic Families – group of organic compounds with common structural features. o Each family has a recognizable physical property and a specific structural arrangement. o Each combination is referred to as a functional group. o Even

certain level of strain (i.e. 12.2 % parallel to carbon-carbon bond and 7.3% perpendicular to carbon-carbon bond) the band gap of graphene increases and then begin to fall . So‚ four different assumptions have been made for angular change of primitive unit vectors for four different regions of applied strain (i.e. before and after the strain of 12.2 % parallel to carbon-carbon bond & before and after the strain of 7.3% perpendicular to carbon-carbon bond). The result obtained in the present study

Experiment B10- Photocromism and Piezochromism Reece Harms 4320288 Introduction This experiment investigates an oxidative coupling reaction in an to synthesise triphenylimidazole dimer from 2‚4‚5-triphenyl-1H-imidazole. The resulting compound was investigated for both photochromic and piezochromic properties by way of formation of a stable radical‚ utilizing visual observations and UV-Vis as a means of distinction. Both the oxidative coupling reaction and the dimers interaction with light

necessary to support life. Here it deals with the nutrition in microorganism which is called as microbial nutrition. Nutrients may be divided into three general‚ often overlapping categories: Those that supply energy‚ those that supply carbon‚ and those that supply any and everything else. In this lecture we will consider nutrition from the point of view of microorganisms‚ though many of the principles apply to macro organisms equally well. According to Webster nutrition

cold and dark‚ and you tend to get carbon and hydrogen fluoride produced. It is of no particular interest. For example: The reaction between alkanes and iodine Iodine doesn’t react with the alkanes to any extent - at least‚ under normal lab conditions. The reactions between alkanes and chlorine or bromine There is no reaction in the dark. In the presence of a flame‚ the reactions are rather like the fluorine one - producing a mixture of carbon and the hydrogen halide. The violence

or group of atoms‚ (FUNCTIONAL GROUP) in their structure. Catenation The ability to form bonds between atoms of the same element. Carbon catenates to form chains and rings‚ with single‚ double and/or triple covalent bonds. Q.1 • Why does carbon form so many catenated compounds ? • Why does silicon undergo catenation to a lesser extent than carbon ? Homologous Series A series of compounds of similar structure in which each member differs from the next by a common repeating unit

Calculate the mass of stearic acid required to form the monolayer‚ use it to estimate the thickness of the monolayer (which is related to the length of the stearic acid molecule)‚ and then use the number of carbon atoms in stearic acid to approximate the diameter and then the volume of a carbon atom calculate a value for the Avogadro constant compare your calculated value for the Avogadro constant with a known value and determine the percent error in your value This is a general overview

Until the discovery of Bucky ball‚ the graphite and diamond were the only molecules formed using carbon atoms. Even though the founder of Bucky ball was curl‚ Kroto and Smalley‚ the fullerene molecule was named after Richard Buckminster fuller (1895-1983) an famous architect‚ because the structure of Bucky ball looks same as that of the geodesic dome
