BOILING POINT G1 Decreases going down. Because metal bonds get weaker. Less energy is required this metallic bonding. BOILING POINT G 17‚18 Increases. Because the atomic size incrases. The molecules are attracted by intermolecular forces. Going down the group‚ the intermolecular forces increases. More energy is needed to overcome these stronger forces. DENSITY Because mass increases faster than volume. REACTIVITY OF GROUP 1 The number of occupied shells increases. The atomic size increases

LAB: Comparison of Reactions for Three Isomers of Butanol /23 TI /21 C /6 A Name: /50 MARKS Background: The reactivity of alcohols can be accounted for by their molecular structure – particularly by the attachment of their hydroxyl functional group. The isomers of butanol are used as examples of 1°‚2° and 3° alcohols to examine this relationship. Each of the three isomers of butanol will be mixed with concentrated hydrochloric acid. The presence of an alkyl halide product is

MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting point. Boiling point

On Saturday‚ December 2nd‚ I saw the Live Newspaper Production of: BOILING POINT! Water‚ Politics‚ and Power. Boiling Point is production directed by Tom Harryman that gave a voice‚ while using satire‚ to show the flaws of how people of power in America deal with problems revolved around water. In this essay‚ I will analyze the audience‚ design‚ theme‚ acting‚ and the spectacle of the play. The audience had a mixed group of people. Even though I did not see anyone under that age of 17‚ I heard a

This lab will allows the comparison between elimination reactions under acidic and basic conditions through an analysis of two separate reactions: an acid-catalyzed dehydration of 1-butanol and 2-butanol using sulfuric acid and a dehydrobromination under basic conditions using potassium tert-butoxide of 1-bromobutane and 2-bromobutane. The products of all four reactions will be analyzed with gas chromatography‚ which separates organic compounds to see how each reaction’s product are formed under

experiment was to investigate the effects of salt type and concentrations on the rate of heating and the boiling point. Then from this data make a conclusion which salt type and concentration is the most energy efficient at heating water to its boiling point. It was hypothesised that highest concentration of MgCl2 was going to be the most energy efficient at heating the solution to its boiling point. This is because MgCl2 has the lowest specific heat capacity thus will use the least amount of energy

Comparison of Three Isomers of Butanol Introduction An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. The location of this hydroxyl functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). The purpose of this experiment is to observe and predict the reactions that take place between all three alcohols and an oxidizing agent‚ as well as to test our theories of how the

Using Freezing-Point Depression to Find Molecular Weight Abstract: In this lab‚ the purpose was to use the freezing point depression method to determine the molecular weight of aspirin. This was done by determining the freezing of t-butanol and that of a t-butanol and aspirin solution; then finding the molality of the solution‚ and moles of aspirin. In the results of the experiment‚ the molar mass was found to be 192.2 g/mol‚ which differed from the established value of 180.2 g/mol by 6.7% error

information about boiling water. If you cover the tin and allow the water and air to cool down‚ the air will cool and contract‚ lowering the pressure in the tin. If it lowers enough‚ the partial vacuum will collapse the walls of the can! The boiling point definitely reduces with air pressure. There is a famous demonstration where boiling water or coffee is drunk‚ the trick is it was in a vacuum chamber where it boiled at room temperature. The actual definition of the boiling point of water is the
