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

Hydrocarbons Jessa Grace B. Castillo* and Stephanie Chua Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines ______________________________________________ Hydrocarbons are organic compounds containing only hydrogen and carbons and further divided in major types. Hydrocarbons react differently in reagents. The basis of determining an unknown hydrocarbon is due to the differences in reactions of hydrocarbons. An unknown compound is determined using tests.

2.2 2.3 Shapes of molecules and ions 2.3a Electron pair repulsion theory a demonstrate an understanding of the use of electron-pair repulsion theory to interpret and predict the shapes of simple molecules and ions In a chemical species like a molecule or ion‚ pairs of electrons create negative centres that surround the central atom. These electron pairs repel each other and arrange themselves to be as far apart as possible‚ thus minimising repulsion.

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:

alkenes‚ alkynes‚ and aromatic hydrocarbons. Because of their relatively non-polarity‚ all hydrocarbons are insoluble in water. When hydrocarbons burn in sufficient oxygen‚ carbon dioxide and water are the sole products. The main structural difference among hydrocarbon families is the presence of double or triple bonds between carbon atoms. The alkanes are saturated organic compounds‚ or those with only single bonds. Unsaturated organic compounds are those which have double or triple bonds. [1] Many

Identification of the side-chains. Side chains are the carbon chains that are not in the parent chain‚ but are branched off from it. 4. Identification of the remaining functional groups‚ if any‚ and naming them by the their ion names (such as hydroxy for -OH‚ oxy for =O‚ oxyalkane for O-R‚ etc.).
