Answer to Question #92741 in Organic Chemistry for Victor Idem

Question

(1) What relationship exist between the following pair of structures?
(a) CH3COCH2CH3 and CH3C(OH)=CHCH3
(b) CH3OCH2CH3 and CH3CH2OCH3
(c) CH3CH2COC3H7 and CH3CH2CH2CH2COCH3
(d) CH3CH2COOH and CH3COOCH3

(2) In one sentence, comment on the physical and chemical properties of (D) 2-bromo butan-2-ol and (L) 2-bromo butan-2-ol

(3) How many isomers are possible for the compound 4-bromo 7-Chloro 4-hydroxy 2,6dimethyl-heptanoic acid

Answer 1

(1)

(a) tautomers

(b) one and the same structure

(c) homologues

(d) isomers

(2) Formally they may be concidered as enantiomers which means they would have same physical and chemical properties except for the opposite rotation of polarized light, but actually these particular structures would be unstable and decompose into butanone-2 and HBr.

(3) 8 stereoisomers Plus enormous amount of all other types of isomers.
