Aliphatic and aromatic
Aromatic compounds are organic compounds having a phenyl group. Aromatic compounds are carcinogenic genetoxic, that there is no safe limit for exposure cancer risk. Examples of the aromatic compound is benzene. While Aliphatic compounds are organic compounds that do not have a phenyl group. Aliphatic compounds are generally highly flammable so it is often used as a fuel. Aliphatic compounds are examples of Methane and Acetylene. Differences between senyawatersebut lies in the presence or absence of the phenyl group. In chemistry, the phenyl group is one of the functional groups in a chemical formula. -The formula is C6H5. In this group, six carbon atoms arranged in a cyclic ring structure. This ring is very stable, and is part of a group of aromatic compounds. Phenyl ring is hydrophobic (water repellent) and aromatic hydrocarbons. This cluster can be found in many organic compounds. The ring is estimated to be derived from benzene.
Hydrocarbons can be classified according to a variety of carbon-carbon bonds they contain. Hydrocarbons with carbon-carbon single bond has called saturated hydrocarbons. Hydrocarbons with two or more carbon atoms having two or three bonds called unsaturated hydrocarbons.Hydrogen and its compounds, generally divided into three major groups, namely:1. Hydrogen consists of aliphatic carbon chain that does not cover cyclic wake. This group is often referred to as the open-chain hydrocarbons or cyclic hydrocarbons. Examples of aliphatic hydrocarbons, namely:C2H6 (ethane) CH3CH2CH2CH2CH3 (pentane)2. Alicyclic hydrocarbon or cyclic hydrocarbon composed of carbon atoms arranged in a ring or more.3. Aromatic hydrocarbons are a special class of cyclic compounds that are usually described as a ring of six with a single bond and a double bond bersilih changed. The group is classified separately from acyclic and aliphatic hydrocarbons because of its unique physical and chemical properties
For saturated hydrocarbons, all of the carbon atoms in the alkane has four single bonds and no lone pairs. The electrons are bound strongly by both atoms. Consequently, these compounds are quite stable and is also called paraffin which means less reactive.Aliphatic hydrocarbons derived from petroleum, while aromatic hydrocarbons from coal. All hydrocarbons, aliphatic and aromatic have three general properties, which are not soluble in water, is lighter than water and burns in air.

What does it mean to be carcinogenic genetoxic Aromatics, which is no safe limit for exposure cancer risk ...?
BalasHapusAromatic compounds are compounds that are carcinogens genetoxic. This means that there is no safe limit for exposure cancer risk. So, just a little exposure to these compounds remain at risk of developing cancer.
Hapusaromatic compounds can cause cancer and if we are contaminated in large quantities then the effect is even more awesome again. the safe use depends on the type of matter itself
BalasHapusCertain polycyclic aromatic hydrocarbons are carcinogenic (ie, the compound causes cancer). These compounds can produce tumors in mice in a short time although only slightly smeared on the skin. This is not only carcinogenic hydrocarbon found in coal tar and soot but also in tobacco smoke and can form in grilled meat. Biological effects have been known for a long time, ie since 1775, when soot is identified as a cause of cancer of the penis chimney cleaning. The incidence of cancer of the heart and lips are also common in smoker.
BalasHapusHow these carcinogens cause cancer now has started to unfold. To eliminate hydrocarbons, the body usually mengoksidasinya order to be more soluble in water, making it easy secreted. Metabolic oxidation product appears to be the major cause of cancer. For example, one of the most potent carcinogens of this type is benzo [a] pirena. Enzymatic oxidation converts it into diol-epoxide as shown in the figure below. Diol epoxide is then reacted with the cell's DNA causing cell mutation that ultimately prevents the normal production.
benzene with strukturyang only have one ring alone possess toxic (poison), which is quite dangerous when used in large quantities. especially if the structure of benzene consists of more than one ring, the nature ketoksi will surely grow again.
