what is 2,4,-dichloro-phenoxyacetic acid and how is it synthesized

Back (Answer)

it is a plant growth control

Front (Question)

what is agent orange and what it is made of?

Back (Answer)

agent orange is a herbicide 50/50 mix of two compounds:

Front (Question)

what is the danger of 2,4,5-T?

Back (Answer)

self reaction can create dioxin, one of the most toxic man made chemicals even though it is in very small quantities (Cl is not a strong EWG for an aromatic substitution) but it can still happen and it can be very dangerous

Front (Question)

what is the LD50?

Back (Answer)

median lethal dose of a toxic substance or radiation (LD50) is the dose to kill half the members of a tested population

Front (Question)

what is the structure of bisphenol?

Back (Answer)

Front (Question)

how can bisphenol be used to make epoxy resin (glue)?

Back (Answer)

continues to form a polymer

Front (Question)

what are applications of epoxy resins?

Back (Answer)

protecting coats in electronic circuit boards adhesives (glues) patching holes in concrete pavement

Front (Question)

how is synthesis of bisphenol A made from phenol?

Back (Answer)

Front (Question)

what is bakelite plastic made from?

Back (Answer)

phenol and formaldehyde

#10

Front (Question)

why are benzene reactions different from alkene reactions?

Back (Answer)

benzenes prefer substitution reactions instead of addition reactions a catalyst and often heat is also often needed for benzene to react

#11

Front (Question)

reminder of the directionality of groups on benzene

Back (Answer)

#12

Front (Question)

how does BHT prevent food from spoling?

Back (Answer)

breaks the chain reactions that spoil food by scavenging peroxy radicals peroxy radicals are the things that cause food spoilage

#13

Front (Question)

what is needed to make epoxy resin?

Back (Answer)

#14

Front (Question)

what is the reaction to make the first polymer part of epoxy resin?

Back (Answer)

#15

Front (Question)

what happens when you mix that polymer with the diamine?

Back (Answer)

#16

Front (Question)

mechanism for synthesis of bisphenol A

Back (Answer)

when you have phenol type thing, you usually get an attack from the para position, then you have water leaving, carbocation, rearomatization etc

#17

Front (Question)

synthesis of bakelite

Back (Answer)

#18

Front (Question)

how does the solvent change the bromination of phenol?

Back (Answer)

#19

Front (Question)

how is BHT made from 4-methylphenol?

Back (Answer)

#20

Front (Question)

why does phenol not undergo O-alkylation?

Back (Answer)

because a C-O bond is less stable than a C-C bond

#21

Front (Question)

how does BHT consume peroxy radicals?

Back (Answer)
