Question

Rank the indicate hydrogens be increasing acid strength. (weakest acid first) What is the relationship between the given structures? H:: H-C=C-C-C-C-H HHH H:9: H H-¢-C-c=ć-H HH-C-H

Answer 1

H I sok MOV rength comparison, we compare the stability of conjugated base. On removing proton (1) gives allylic as well as benzylie anion which is resonance stablired. Therefore it is most acidic Then proton (II) on deprotonation gives vinglic ne sp² hybridised Carbanion where 33y iss character and for proton I') an sp3 hy bridised Carbawion, 254 s. Charactor is formed.

higher the ys Character, wigher is the stabity of carbonion as the order of actity will be На с нр< Нат

Sol HC = CH CH2 - CH2 Heren qack Both are have some chemical formula of Cg Ago and some functional group only the position of double bond is different and also the c- skeleton. a. they are structural isomers.
