theretore tnkes more enargy to stretch it. The C-O bond of the aloohol in stronger then the C - O bond the carboxylic acid and therelore fakes less energy lo saratch it. The CO bond of the aloohol is a pura tingle bond, in contiast, the C - O bond of the carboxylic acid has double-bond character, soit is a aurongor bond and theroloro takes more energy to stretch it. Tho CO bond of the capbexylie acid is moce polar than the C - O bond of the alcohol, so tho C - O bond of the carboxyier acid in a stronger bond and therelore tintes more energy to stroteh it
