The following bimolecular elimination reaction `(E_2)` is carried out with different halogen leaving groups. The per cent yield of the two products (2·hexene and I-hexene) for each leaving group is listed below.

Which ofthe following statement is (are) true concerning this series of `E_2` reactions?

A

Based on the `pK_s` 's of the conjugate acid `,I^-` is the best leaving group and `F^-` is the pooreset leaving group

B

When `I^-Br^- "and" Cl^-` are used as leaving groups, Zaitsev's rule is followed.

C

`F^-` is the stronger base (and therefore the poorest leaving group) and the transition statefor reactionwithfluoride as theleavinggrouphas theleastdoublebondcharacter

Amines are less reactive in substitution reactions. Their reactivity is much lesser than alcohols and alkylflourides towards substitution. Protonation of the amino group makes it a better leaving group, but not nearly as good a leaving group as a protonated alcohol. Protonated amino groups cannot be displaced by OH^(-) because it would react immediately with the acidic hydrogen which would convert it in to a poor nucleophile. The leaving group in quartenary ammonium ion has about the same leaving tendency as a protonated amino group but does not have acidic hydrogen. The reaction of a quartenary ammonium ion with hydroxide ion is known as Hoffmann elimination reaction. The leaving group is tertiary amine. Since a tertiary amine is only a moderately good leaving group, the reaction requires heat. The carbon to which the tertiary amine is attached is designated as alpha carbon. When the hydroxide ion starts to remove a beta H from a quartenary ammonium ion, the leaving group does not immediately start to leave because a tertiary amine is not a good leaving group. As a result, a partial negative charge builds up on the carbon from which the proton is removed. Which of the following statements are true regarding Hoffmann elimination ?

Electrophilic substitutions are characteristic reaction of aromatic compounds. In this reaction hydrogen of the aromatic ring is replaced by an electophile because hydrogen in the form of HR is very good leaving group. -COOH and -SO_3H are also good leaving groups when they are present either at ortho or at para to the highly activating groups like -NH_2 and -OH. Which one of the following compounds will be most unreactive towards electrophilic substitution reaction?
