Problem 4.1 Three components of the sex pheromone of the female sand bee Ophrys sphegodes) are saturated hydrocarbons containing 23,25, and 27 carbon atoms. How many H atoms does each of these alkanes contain Interestingly, the early spider orchid emits a similar hydrocarbon mixture to attract male sand bees to pollinate its flowers.
