Question

What is the major organic profucy expected from the following reaction? (more questions below if you can help it would be much appreciated!!)

What is the major Organic product expected from the following reaction? OH оно ci CH:CH OH OH OCH.CH O CI H3CH,CO (6) OH (d) (1) a. a b.b c.c d.d e. e f. f

Answer 1

8n the acidic H of -o-H gets obstracted which gives (1) ои ой CI сиз СН,ои with nucleophilic substitution reáchon in intramolecular fashion. Mechaniama 'ОИ CI - Иор CI | is correct so option (9)

So higher the stability of formed Carbocation higher will be rate the Sus reaction occur via carbocatton reaction intermediate >> of SNL. Bens ylic Carbocation (stablided by th effect) 4 Сиз оr → CM3 (c) fr vinylic carboration (d) CH3 сиз it BY -CM3 HC he 3º carbocation (stablized by 92H) So most stable Highest Hyper Conjugation ethyl Carbocation le) Cha Chy By Спа си, d) go carbocation. In general the th effect dominates over Hyber conjugation for the stability of carbocation. but here due to 9 LH and 3° carbon is most stable so ch3 0 Jastest SNI ne "Ch₃ op him (d) is correct.

(3) with Nani Sodium salt of ferminal alkyne formed which gives nucleophilic substitution reactionat alkyl chloride. ING =6* май THE -M₂ -NaCl sooption (f) f is correct. final product (4) (4) with diazorethane carboxylic acid fooms corresponding methy) ester -CH₂ OH (H₂N2 •OCH₃ is correct So option (9)
