Unsaturated organic compounds : Organic compounds in which a double or a triple bond exists between two carbon atoms in a carbon chain‚ are called unsaturated organic compounds. 10. Hydrocarbons : Organic compounds which contain only carbon and hydrogen atoms are called hydrocarbons. 11. Straight chain hydrocarbons : Hydrocarbons‚ in which all the carbon atoms are linked to one another in a straight chain by a single covalent bond are called straight chain hydrocarbons. 12. Branched chain hydrocarbons

What is hairspray made of? Hairspray is a solution of long‚ chainlike molecules (called polymers) in a very volatile solvent. Spraying deposits a stiff layer of the polymer on your hair after the solvent evaporates. The solvent used was once a compound of carbon‚ fluorine‚ and chlorine (a chlorofluorocarbon‚ or CFC). CFCs are nontoxic‚ nonflammable‚ and make almost ideal aerosol propellants. But when it was learned that they causedestruction of stratospheric ozone‚ they were replaced with other

purpose? Cannizzaro reaction is a reaction that uses a strong base‚ such as sodium hydroxide‚ which results to the formation of a carboxylic acid (or its corresponding salt) and an alcohol. It is only observed in aldehydes that do not contain alpha hydrogen atoms. Aldol condensation is a reaction in which an enolate ion reacts with a carbonyl compound to form an α-hydroxyaldehyde or β-hydroxyketone‚ followed by a dehydration to give a conjugated enone. c) Provide the type equations used in the test

AB ? A + B The electrolysis of water into oxygen and hydrogen gas is an example of a decomposition reaction: 2 H2O ? 2 H2 + O2 Single Displacement or Substitution Reaction A substitution or single displacement reaction is characterized by one element being displaced from a compound by another element. A + BC ? AC + B An example of a substitution reaction occurs when zinc combines with hydrochloric acid. The zinc replaces the hydrogen: Zn + 2 HCl ? ZnCl2 + H2 Metathesis or Double Displacement

Experiment 6 Infra-Red Spectroscopy of HCl and DCl gas Abstract Fourier-transform infrared spectroscopy has been very useful in helping scientists examining molecules of HCl and DCl. Because deuterium has a greater mass than hydrogen‚ the IR band shown for HCl is at a higher wavelength than DCl. The absorption of light in DCl was at lower frequency 1700-2200 cm-1 because D is bigger and heavier. That’s why the vibrations on the IR were shorter for DCl compared to HCl. The stretching of

lab is to identify the given unknown organic compounds with various methods. Identification of an unknown compound is important to perform through the process of melting point (M.P)‚ boiling point (B.P) and Infrared spectroscopy (I.R). Index of Hydrogen deficiency (IHD) and elemental analysis makes an experiment more efficient in determination of unknown compound. The color‚ odor‚ melting point and boiling point determines the physical state and properties of a compound. It also determines its volatility
