How many electrons do these elements have in their outer orbit? b) Bromine has the same chemical behaviour as chlorine and fluorine. Where is bromine found on the periodic table in relation to chlorine and fluorine? c) How many electrons do you suppose that bromine has in its outer orbit? 5a) Helium‚ neon‚ and argon behave similarly in chemical reactions. What do you notice about the outer orbit of electrons in

Chlorine is more reactive than bromine.This mean that chlorine can displace bromine in the compound sodium bromide and make sodium chloride plus bromine.Another example is that fluorine can displace chlorine.This is how the halogens can displace each other chlorine + sodium bromide → sodium chloride + bromine Task 2 There are two types of bonding.Covalent bonding and ionic bonding. Ionic bonding occurs from positively ions and negatively

Metals and Halogens reactions Elements such as fluorine‚ chlorine‚ bromine‚ iodine‚ and astatine belong to Group 7‚ Halogens. At room temperature‚ fluorine is a yellow gas‚ chlorine is a pale green gas‚ bromine is a red liquid‚ and iodine is a purple solid. Astatine is a radioactive element‚ therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make

Discussion and Conclusion: Preparation of 1-Bromobutane The purpose of this experiment was to demonstrate the conversion of a primary alcohol‚ 1-butanol‚ to a primary bromoalkane‚ 1-bromobutane‚ a SN2 reaction. The conversion of 1-butanol to 1-bromobutane relies on sulfuric acid which plays two important roles. First‚ it protonates the alcohol of 1-butanol to form an oxonium ion which is a good leaving group. Secondly‚ it produces the hydrobromic acid‚ the nucleophile‚ which attacks 1-butanol

represented by 5Br—(aq) + BrO3—(aq) + 6H+(aq) → 3Br2(aq) + 3H2O(l) The progress of the reaction may be followed by adding a fixed amount of phenol together with some methyl red indicator. The bromine produced during the reaction reacts very rapidly with phenol. Once all the phenol is consumed‚ any further bromine bleaches the indicator immediately. So‚ the time for the reaction to proceed to a given point may be determined. Requirements: Apparatus: Beaker Burettes Boiling tubes Stop-watch

Objective: The purpose of this lab was to use transfer hydrogenation to saturate glycerol trioleate (the main fat in olive oil) to produce glycerol tristearate. Reaction Equations: Theoretical Yield: There was no Theoretical yield in this experiment Procedure: Fill a 50 mL beaker with 30 mL of water and place it on the hot plate. Add 14 drops of olive oil to a 10 mL round bottom flask and then add 1 mL of cyclohexene. Add .05 grams of 10% palladium-on-carbon to the round bottom flask

Cyclohexene From Cyclohexanol 5/29/14 Abstract: A 42.89% yield cyclohexene was successfully synthesized from 10.0 mL cyclohexanol by unimolecular elimination (E1) through the dehydration of cyclohexanol and confirmed via a bromine test and the IR spectra. Introduction: Alkenes are hydrocarbons that have carbon–carbon double bonds and are one of the many functional groups in organic molecules. Alkenes are sp2 hybridized and are unsaturated because two of their hydrogen’s
