Question

Oleic acid and eladic acid are naturally occuring compounds which are isolated from various oils and fats.
Both diastereomers have one double bond at `C-9`. Oleic acid is cis and eladic acid is a trans isomer at `C-9`. Both have molecular formula `C_(17)H_(33)COOH`. Synthesise both from ethyne.

Answer 1

Write the structure of oleic and eladic acid.
`(C=C)` bond at `C-9`.
Total C atoms `=(17+-COOH)=18C`
