(a)
Interpretation: The structure of stereoisomer that has higher melting point than eleostearic acid is to be drawn.
Concept introduction: Fatty acids are of two types: saturated fatty acid and unsaturated fatty acid. In Saturated fatty acid, double bond is absent, whereas unsaturated fatty acid consists of one or more than one double bond. The melting point of a fatty acid indirectly depends upon the number of double bond present in an acid. Higher is the number of double bonds in acid, lower will be the melting point of an acid.
When two higher priority groups are present on the opposite side then it is an
(b)

(a) Label each substituent on the rings as axial or equatorial. (b) Draw B using chair conformations for each sixmembered ring. (c) Label the atoms on the ring fusions (the carbons that join each set of two rings together) as cis or trans to each other.arrow_forward
- Explain why A is less water soluble than B, even though both compounds have the same functional groups.arrow_forwardTautomers A) are resonance forms of carbonyl compounds. B) are always equally stable. C) require a strong base for interconversion. D) are constitutional isomers.arrow_forward2. (a) Ozonolysis of compound A, CH12 gave two products B and C. Further analysis of these two compounds of B and C, showed positive results with 2,4-dinitrophenylhydrazine. Compound B reacts with Tollens' reagent while compound C does not indicate any positive result to the same reagent. However, both B and C gave same positive results with iodoform test.arrow_forward
