Question
Which would be water-insoluble?Question 9Answera.Methanalb.Acetonec.Ethanald.Nonanal
Solution
The water-insoluble substance among the options provided would be nonanal.
Here's why:
a. Methanal (Formaldehyde) - It is a polar molecule and hence, it is soluble in water.
b. Acetone - It is also a polar molecule and hence, it is soluble in water.
c. Ethanal (Acetaldehyde) - It is a polar molecule and hence, it is soluble in water.
d. Nonanal - It is a long chain aldehyde. Although it has a polar aldehyde group, the long hydrocarbon chain makes the molecule overall non-polar. Non-polar molecules are not soluble in polar solvents like water. Hence, nonanal is water-insoluble.
