hydrocarbons are the alkanes which contain only single covalent bonds. Methane is the simplest alkane. It is also the major component of natural gas. Methane contains only 1 carbon in the molecular formula and the structural formula. There is ethane which is 2 carbons‚ propane that is 3‚ butane which is 4‚ pentane which is 5 and so on. There are also alkenes. Alkenes are hydrocarbons containing carbon-carbon double covalent bonds‚ and last but not least there is the alkynes which are hydrocarbons

organic compounds can be derived into two broad classes 1. Aliphatic compounds Nonaromatic hydrocarbons such as alkanes‚ alkenes or alkynes 2. Aromatic compounds A series of cyclic unsaturated compounds with unusually high stability • The properties and reactions of aromatic compounds are exemplified / demonstrated by the properties and reactions of benzene (the “parent” aromatic molecule) • Benzene Structure: MF: C6H6 DBE = • Properties and Reactions of Benzene 1.

of the main alkanes‚ alkenes‚ alkynes and cyclic hydrocarbons. Procedure: 1. Complete the following table with similarities and differences in hydrocarbons. 2. From the table set examples of compounds in their condensed formula‚ naming them correctly. 3. Search for information about an alkane. Indicate where it comes from‚ its uses‚ effects in the environment and the way we can avoid negative impacts of this compound. Results: 1. HYDROCARBONS Alkanes Alkenes Alkynes Cyclic H. Similarities

hexagonal ring of carbon called as benzene in their molecule. Aromatic hydrocarbon can contain one or more than one benzene ring. Those compounds which contain more than one benzene ring are known as polynuclear aromatic hydrocarbon like naphthalene‚ anthracene etc. The aromatic compounds are generally taken as derivatives of benzene. Benzene and its derivatives are mainly used in synthetic organic chemistry. The main source of polynuclear aromatic compounds is coal tar. For example‚ naphthalene is the

* Introduction to Organic Chemistry Understand the basis of drawing organic structures Depicting 3-D structures in 2-D Most organic compounds have a three-dimensional structure. How do we represent structures on our two-dimensional page? For example‚ methane is a tetrahedral molecule: Bonds in the plane of the paper: Bonds coming towards the observer: (out of the page) Bonds going away

covalent bonds. Alkanes Alkanes are hydrocarbons‚ which are molecules that contain only carbon and hydrogen. They are made up of carbon atoms linked together by only single covalent bonds and are known as saturated hydrocarbons. Many alkanes are obtained from crude oil by fractional distillation. The smallest alkanes are used extensively as fuels. Apart from burning‚ however‚ they are remarkably unreactive. Alkane Methane Ethane Propane Butane Pentane Alkene Ethene Propene

R OH R R OH OH R secondary tertiary phenol Alcohols with the hydroxyl bound directly to an aromatic (benzene) ring are called phenols. Nomenclature of Alcohols (Normally any compound’s name which ends in –ol is an alcohol of some sort) IUPAC rules that: (1) Name the longest carbon chain bearing the –OH group. Drop the last –e from the alkane name and add –ol to obtain the root name. (2) Number the longest chain starting at the end nearest the –OH group‚ and designate

Organic Chemistry - Introduction 1 2812 Basic definitions for organic chemistry Scope Organic chemistry is a vast subject so it is easier to split it into small sections for study. This is usually done by studying compounds which behave in a similar way because they have a particular atom‚ 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
