The purpose of the OTS (Organization for Tropical Studies) is to promote research, education, and conservation in tropical ecosystems. It supports its members by providing access to research facilities, field courses, and networking opportunities to enhance their understanding and work in tropical environments.
Here are some organic chemistry synthesis practice problems for Orgo 1 students: Synthesize 2-methylpentane from 1-pentene. Synthesize 2-bromopropane from propene. Synthesize 2,4-dimethylhexane from 1-hexene. Synthesize 2-chloro-2-methylbutane from 2-methyl-1-butene. Synthesize 3-ethyl-2-methylhexane from 1-hexyne. These problems will help students practice their skills in planning and executing organic synthesis reactions.
Yes, H2SO4 and SO4-2 are a conjugate acid-base pair. In this pair, H2SO4 is the acid that donates a hydrogen ion (H+) to become its conjugate base, SO4-2, which is the resulting species after losing a proton.
you have it backwards. SN2: you want a polar APROTIC solvent. Protons are bad because they would solvate (surround) and stabilize the nucleophile, making it less reactive. SN1: you want a polar PROTIC solvent. Protons are good because they will solvate (surround) and stabilize the leaving group as it leaves. This lowers the energy of the transition state and makes the reaction go faster. a final teaching point: recognize that your question essentially is about what makes the reaction go faster, which is a question of KINETICS, NOT THERMODYNAMICS (if you want to be good at orgo, this concept is VERY IMPORTANT). You will make the reaction go faster by stabilizing the transition state of the rate limiting step. The transition state of the rate limiting step in an SN1 reaction is the leaving group leaving (the nucleophile is NOT involved, therefore, it does not matter that it is solvated). That of an SN2 reaction is the nucleophile attacking the carbon center as the leaving group is leaving (the nucleophile IS involved, so it must not be solvated).

"i may not be the best kisser in the world but i will put my lips up against yours any time" that's what orgo said
he was pressing his luck
he was pressing his luck
He was trying to get
He high jacked it
he had a lot on his mind or hehadalotonhismind
The tickets were all square.
She told him to keep his strap shut.
