A linear polymer of D-glucose joined only by alpha-1,4 links has molar mass $16200 g mo l^{- 1}$ (treat it as exactly $n \times 162$ , the mass of $n$ units of $C X_{6} H X_{10} O X_{5}$ , ignoring the end groups). The number of glycosidic bonds hydrolysed on complete hydrolysis is

The number of units is

n = 16200/162 = 100

. A linear chain of

n

units has

n - 1

glycosidic bonds, so

99

bonds are broken.
