Question

During hydrolysis, ___________ must be added before the bonds can be broken. (look at flash animation on hydrolysis)

Answer 1

water must be added to break the bond

Answer 2

The correct answer is water.

During hydrolysis, _____water______ must be added before the bonds can be broken.

For example, sucrose undergoes hydrolysis to break into glucose and fructose. Here sucrose is a disaccharide and glucose and fructose are monosaccharides.  

Sucrose + H₂O → glucose + fructose

Esters are formed by the combination of carboxylic acid and alcohol.

But the hydrolysis of ester causes the release of carboxylic acid and alcohol.

RCOOR'(ester) + H₂O → RCOOH(carboxylic acid) + R'OH(alcohol)
