Question

Glucose or sucrose are soluble in water but cyclohexane of benzene are insoluble in water explain

Answer 1

Glucose and sucrose are soluble in water but cyclohexane of benzene are in soluble in water because of the absence of —OH groups and hence, they do not form H-bonds with water .

Answer 2

Answer:  In glucose molecule  (C₆H₁₂O₆) , five - OH group are present and in Sucrose (C₁₂H₂₂O₁₁) , eight - OH groups are present. Thus, glucose and sucrose undergo extensive H-bonding with water. So these compounds are readily soluble in water .

But, Benzene (C₆H₆) and Cyclohexane (C₆H₁₂) do not contain −OH groups. So they can't make hydrogen bonds with water therefore , they are insoluble in water .
