I need help with problems with 5 and 6. I'm not sure how to do them. Thanks! 5. the stability of carbocations is generally explained by a concept known as hyperconjugation. Use this concept to explain why a primary (1°) carbocation is more stable than a methyl (CH3+) carbocation. You must use a simple and concise drawing to show your point. 6. Using frontier orbital theory, explain why an E2 reaction must have the beta-hydrogen and the leaving group anti-periplanar...

1. In both the sodium iodide
test and the silver nitrate test, why does 2-bromobutane react
faster than 2-chlorobutane?
Bromine is a better leaving group since it is a weaker base than
chlorine is.
2. a. Why does benzyl chloride react under both
SN1 and SN2 conditions?
Benzyl
chloride is a primary alkyl halide, hence reactive under SN2
conditions.
The
primary carbocation formed due to the departure of Cl- is
stabilized by the pi electrons in the benzene ring.
b. Why is...

5. (20 pts) Suppose on a given college campus 45% of the students own an iPhone, 50% an Android smartphone and 5% some other type of phone. Let X=the number of students in a simple random sample of 15 students who own an iPhone. A. What is the probability distribution of X? Note: If this is a well-known distribution it is sufficient to name the distribution and identify the value of the parameters B. Find the probability that 8 students...

According to Robert Trivers, why are men generally larger and more physically aggressive than women? Because women are more reproductively “valuable” than men, hence competition for mates is fiercer among men Because men invest more heavily in reproduction than women Because men secrete more testosterone Trivers’ theory does not speculate on the origin of the sex difference in size and physical aggression Although some women are interested in casual sex (short-term mating), research has suggested that there are differences in...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
