agriculture—and am receiving a box of organic produce delivered to my doorstep every week. My reasons for doing this are as follows: I want to eat locally grown produce; I want to reduce the use of chemicals in the food I eat; I want to reduce my carbon footprint by buying local‚ non-corporate food; I prefer to support local farmers‚ especially in a down economy; by subscribing rather than just buying at a farmer’s market‚ I’m showing my commitment to organic farming; and I will eat a broader range

Physical Properties of Organic Molecules Abstract Identifying the physical properties of compounds can be useful in several ways. It helps us to determine the structure of certain compounds‚ the purity of substances and if a substance is not pure we can figure out how to separate contaminating substances from a compound. In this experiment‚ I learned how to determine a solid’s melting point and why some melting point ranges may be broader than others.

We all know that each country has its own currency (except in Europe where a group of countries have a common currency). The rate at which we can convert one currency into another currency is know as conversion rate between those two currencies. Therefore‚ if I have Rs1‚000/- with me and I wish to get US $ by surrendering the above INR‚ I need to go to a bank or an authorized currency dealers for this transaction. They will convert my INR into US$ at that day’s rate. Thus‚ it becomes clear

8. Terfenedine is an amino diol that is the active ingredient in the antihistamine Seldane. Mass spectral analysis of terfenedine shows a molecular ion at m/z = 471 and a peak at m/z = 472 which is 35.5% the height of the molecular ion. Terfenedine is known to contain C‚ H‚ O and N. (a) Suggest five molecular formulas for terfenedine. (b) Terfenedine has an even number of carbons and contains nine double bonds and four rings. Based on this additional information‚ what is the formula for terfenedine

In the IUPAC system of nomenclature‚ functional groups are normally designated in one of two ways. The presence of the function may be indicated by a characteristic suffix and a location number. This is common for the carbon-carbon double and triple bonds which have the respective suffixes ene and yne. Halogens‚ on the other hand‚ do not have a suffix and are named as substituents‚ for example: (CH3)2C=CHCHClCH3 is 4-chloro-2-methyl-2-pentene. If you are uncertain about the IUPAC rules for nomenclature
