The compound whose structure is CH3(CH2)3C=(O)OH?

Question

A. is insoluble in water, but soluble in aqueous solution

B. is appreciabley souble in water at room temperature

C. is readily oxidized by reagents such as KMnO4 or K2Cr2O7

D. is readily dehydrated by sulfuric acid

Answer 1

B. is appreciabley soluble in water at room temperature...

All the other answers don't make sense! ;-) Well, 'A' definitely doesn't make sense to me. 'C' is not true since a pentanoic acid (the compound in question) is already fully oxidized. And 'D' is not true - H2SO4 will not dehydrate an acid...
