Why are the higher carboxylic acids practically odourless?
AThey exist as volatile gases
BThey are low-volatility waxy solids
CThey are all ionic salt crystals
DThey react readily with air
Answer & Solution
Correct answer: B. They are low-volatility waxy solids
The long hydrocarbon chain makes them waxy solids that hardly evaporate, so little odour reaches the nose.
