Concept Introduction:
Terpenes are made by joining five-carbon units, usually in a head to tail-fashion.
Monoterpenes are those terpenes with two isoprene units-have 10 carbons, sesquiterpenes have 15 carbons, diterpenes have 20 carbons, triterpenes have 30 carbons and tetraterpenes have 40 carbons.
Isopentenyl pyrophosphate (isoprene) is the five-carbon compound used for the biosynthesis of terpenes.
Isoprene unit:

When 'X' is treated with a deuterated acid (D2O), a single deuterium atom replaces a hydrogen atom, forming compound 'Y' (C5H7DO2). 'X' does not react with 2,4-Dinitrophenylhydrazine (2,4-DNP) but does react with both Tollens' reagent and Benedict's solution, forming a silver mirror and a red precipitate, respectively. Furthermore, 'X' undergoes catalytic hydrogenation over a palladium catalyst, consuming one mole of hydrogen to form a compound 'Z' (C5H10O2).
