In the bromination of trans cinnamic acid, a reaction called electrophilic aromatic substitution takes place. This involves the addition of a bromine atom to the benzene ring of the cinnamic acid molecule. The bromine atom acts as an electrophile, meaning it is attracted to the electron-rich benzene ring. This reaction is typically carried out in the presence of a catalyst, such as a Lewis acid, to facilitate the addition of the bromine atom to the benzene ring.

Explain why the addition of bromine to trans-cinnamic acid takes place more slowly than the addition of bromine to a normal alkene like 3-hexene or cyclohexane?

The addition of bromine to trans-cinnamic acid occurs more slowly than to a normal alkene due to the steric hindrance caused by the phenyl group in cinnamic acid, which restricts the approach of the bromine molecule. The resonance stabilization of the double bond in cinnamic acid also hinders the electrophilic attack of bromine, making the reaction slower compared to a normal alkene with no such effects.


What is more polar either cis or trans?

cis. In cis, the electronegativity is concentrated on one side of the isomer, resulting in a net dipole moment, hence it is polar. In trans, the electronegativity is cancelled out by substituent groups on opposite sides of the isomer, there is no net dipole moment, and thus, it is non polar.


Why are there three isomers of dibenzalacetone?

There are three isomers of dibenzalacetone because of the different possible arrangements of the benzene rings and the carbonyl groups on the central carbon atom. These configurations lead to geometric isomers, where the relative positions of the benzene rings and carbonyl groups differ, resulting in three distinct isomeric forms.

Does 3-hexene have cis and trans isomers?

Yes, 3-hexene can exist as cis-3-hexene and trans-3-hexene isomers. In the cis isomer, the two alkyl groups are on the same side of the double bond, while in the trans isomer, they are on opposite sides.

What where the similarities of the trans Atlantic slave trade and trans Saharan trade?

Both the trans-Atlantic and trans-Saharan slave trades involved the forced transportation of individuals for labor purposes across vast distances. Slaves in both trades faced extreme exploitation, abuse, and dehumanization. Additionally, both trades had lasting social, economic, and cultural impacts on the regions involved.

How do you remove headrest on a 1987 Pontiac trans am?

You have to have a very slim tool, I happened to have a very slim and narrow spatula, slide it down the front of the headrest support until you hit the mechanism inside and then pull it off while pushing down on the mechanism.

Which nations were involved in the trans atlantic slave trade?

One can't really speak of "nations" in terms of Africa at that time, but most of the West coast from present-day Mauritania to Angola was involved. These were the suppliers. They met ships from Portugal, Britain, France, Spain, the Netherlands, and America (in order of volume) and sold the slaves for trans-shipment.


Was Trans Canada Airlines involved with the original setup of the Canadian Broadcasting Corporation?

No, both Trans-Canada Airlines and the Canadian Broadcasting Corporation have roots in the Canadian National Railways (CN Rail), but both are independant Crown Corporations.


The different between transahara and trans Atlantic slave?

Trans-Saharan slavery involved the exploitation of individuals across the Sahara Desert region, while Trans-Atlantic slavery was the forced migration of Africans to the Americas for labor on plantations. The former often resulted in individuals being taken as domestic servants or concubines, whereas the latter predominantly involved agricultural labor on sugar, cotton, and tobacco plantations.
