reaction that removed the pi bond from a molecule and adds covalent bonds with two new compounds. Halogenation or most commonly known as bromination is a reaction that breaks a pi bond and adds a halogen or in this case‚ a bromine to the molecule. This addition of the bromine can be very steroselective. Stereoselectivity can come from steric and electronic effects. Steric effect arise when two atoms ar brought close together‚ the resulting push of electrone clouds is what creates the significant

When 4-methylcyclohexanol was combined with the bromine solution‚ the mixture turned into a light yellow color versus 4-methylcyclohexene with the bromine solution being colorless; the initial color for 4-methylcyclohexanol was combined with the bromine solution was a light orange/brown color. The solution being colorless indicated a positive sign of a double bond being present in 4-methylcyclohexene

Synthesis of Triphenylmethanol Hai Liu TA: Ara Austin Mondays: 11:30-2:20 Abstract: In this experiment‚ phenylmagnesium bromide‚ a Grignard reagent was synthesized from bromobenzene and magnesium strips in a diethyl ether solvent. The Grignard reagent was then converted to triphenylmethanol‚ a tertiary alcohol with HCl. The reaction for phenylmagnesium bromide was: The reaction for Grignard to triphenylmethanol was: In the formation of the Grignard reagent‚ the limited reagent‚ magnesium

Report Introduction Mummification is an ancient Egyptian method which is a natural or deliberate process intended to dehydrate the body to preserve it. They done this because they believed that if a body was left to rot then it would destroy their soul‚ so they believed that the body needed to be intact to serve as host for the soul. So they preserved bodies so they could use them in the afterlife‚ where the Egyptians believed they would make a journey to another life. To start to mummify a body
