Organic Chemistry
Consider the following reaction:
Identify this reaction as one of the following three types:
Identify whether the following reaction is an example of substitution, elimination, or neither. Recognize the nucleophiles and/or leaving groups involved in this reaction (if any).a. CH3—CH(Br)—CH2(Br) + KI → CH3—CH=CH2 + IBr + KBr
Classify the given reaction as elimination or substitution. Also, point out the nucleophile or leaving group (if any).
Determine the stronger base between (i) and (ii). Rationalize your choice using the concept of element effect.
Choose the stronger base between 1 and 2. Justify your choice without the use of p Ka values.
Choose the stronger acid between cyclohexylmethanol and cyclomethanethiol. Explain your answer in terms of element effects.
