Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

Question Explanation: Question is asking about the synthesis reaction. Concept: This question is based on Electrophilic Addition of alkene (Hydration of Alkenes).

Solution:

Option (1): It describes hydroboration oxidation of alkene followed by intramolecular SN² reaction.  (Correct)

Option (2): The reagents adds water across a double bond, forming a Markovnikov addition alcohol without rearrangement (Oxymercuration-demercuration OMDM). Final product is formed by intramolecular SN² reaction. (Correct)

Option (3): This is acid-catalyzed hydration of isobutene, forming tert-butanol — Markovnikov addition. (Correct)

Option (4): Aryl halides (Ph–Br) does  not undergo SN² reactions , so the given product cannot be formed. (Incorrect)

(i)

(ii)
