PPT-Alkene Reactions

Addition Reactions Addition is the opposite of elimination A pi bond is converted to a sigma bond Addition Reactions A pi bond will often act as a Lewis base as a nucleophile or as a Brønsted. DEFINITIONS AND TYPES. Revision:. DO NOT WRITE- FOR YOUR INFO ONLY. We have looked at the period table, what atoms are, elements and compounds. You have learnt that atoms can join to make compounds or molecules and that we can mix compounds to make new compounds…..these are chemical reactions. The relative stabilities of related alkenes can be determined by measuring their heats of combustion.. The thermodynamic stability of the butenes increases in the order: 1-butene < cis-2-butene < trans-2-butene.. London. Dr. . Ed . Marshall, M220, RCS . 1. e.marshall@imperial.ac.uk.

Dissolve the sample in DCM (1 mL). Add . dropwise. a 1% . bromine solution. of DCM. Positive test, if red color disappears . Conclusion:. The sample contains a multiple bond, which undergoes .

Draw the condensed or line-angle structural formulas and give the names for the organic products of addition reactions of alkenes. Draw a condensed structural formula for a section of a polymer.. Types of Reactions. Types of Reactions. There are . 9. . main types of reactions we will examine:. Combustion. Substitution. Addition. Halogenation. , . Hydrogenation, . Hydrohalogenation. , Hydration. Chemistry so easy, even a physicist could do it!. -Charles Hoyle. 3. rd. & 4. th. block. Chemistry. November 1, 2011. 1 spider. 8 feet. 1 shoe. 1. 1 spider. 1 foot.

Know the structure, hybridization and bonding of alkenes . . The . risk for development of a drug eruption is related to the following factors: age, gender, dose, and the nature of the medication itself. . Females . are . 1.3-1.5 . times more likely to develop drug eruptions, except in children under the age of 3 where boys are more likely to be affected. . Our estimates of pressures and temperatures experienced by rocks during metamorphism are based on metamorphic reactions.. Mineral Reactions. There are two basic types of mineral reactions:. Continuous. These are the OPPOSITE of neutralization reactions (i.e. acid-base reactions). Rather than forming a salt and water from an A-B reaction, a salt and water react to form an acid and a base.. You MUST determine if you have a Strong or Weak Acid and a Strong or Weak Base..
