reactions in organic chemistry and was first investigated by Otto Diels and Kurt Alder in Germany. It is a [4+2] concerted cycloaddition reaction which involves a diene and a dienophile. The Diel-Alder reaction are mainly used for creating new carbon-carbon bonds‚ mostly involved in forming rings which is does easily. The rings that are formed are stereospecific which is a key characteristic in these reactions. The Diels-Alder reaction is considered a pericyclic reaction which means the electron

reaction‚ a bond is formed between two molecules and creates water as a byproduct. Aldol condensation is a C-C bond forming reaction between the alpha Carbon of the aldehyde or ketone and carbonyl carbon of another ketone or aldehyde. Aldol condensation is different from aldol condensation reaction. For aldol addition reaction‚ the alpha carbon of one aldehyde or ketone adds to the carbonyl group of the other ketone or aldehyde. This process creates a beta-hydroxy carbonyl‚ which is called aldol

Unit 1 Key Questions Lesson 1 1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. On the other hand

Variables: Independent variable: the mass of the beans Dependent variable: the different types of beans Control: The beans Purpose: The purpose of the lab is to find equal measurement of each type of bean. After you find the mass of each bean you need to find the relative mass of each bean. The navy bean will have the smallest relative mass. You will need to wear safety goggles and a lab apron and wash hands after the lab is finished. If you drop any beans pick them up immediately to prevent

dipole forces increase with increasing molecular weight‚ so the boiling points of the straight chain alkanes increase as the number of carbon atoms in the chain increases. Therefore pentane‚ CH3CH2CH2CH2CH3‚ has a higher boiling point than butane‚ CH3CH2CH2CH3. For the same reason‚ the boiling points of the straight chain alcohols also increase as the number of carbon atoms in the chain increases. Therefore butanol‚ CH3CH2CH2CH2OH‚ has a higher boiling point than propanol‚ CH3CH2CH2OH. Because

It is often shortened to MCT oil. The individual members of this class of fatty acids were named for the length of their carbon chain. They have between six and twelve carbons. Fatty acids with more than twelve carbons are classified as long chain triglycerides (LCT). Fatty acids with fewer than six carbons are called short chain triglycerides (SCT). Coconut oil and palm oil are both naturally high in medium chain triglycerides. Sometimes people get confused about

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:
