Explain why :
(i) Glucose is soluble in water but cyclohexane is not.
(ii) Aldehyde group is absent in the pentaacetate of D-glucose.

How do you explain the absence of aldehyde group in the pentaacetate of D-glucose ?

Explain why low molecular mass alcohols are soluble in water ?

Explain why ionic compounds are soluble in water but insoluble in organic solvents?

Why is I_2 more soluble in KI than in water?

Glucose or sucrose are soluble in water but cyclohexane or bezene (simple six membered ring compounds) are insoluble in water. Explain.

In addition to an aldehyde group, glucose contains:

Assign reason for the following : (i) Ammonia is soluble in water while phosphine is not (ii) B_(2) is paramagnetic while C_(2) is not.

Which of the following reactions of glucose can be explained only by its cyclic structure? (a)Glucose forms pentaacetate (b)Glucose reacts with hydroxylamine to form an oxime (c)Pentaacetate of glucose does not react with hydroxyl amine (d)Glucose is oxidised by nitric acid to glyconic acid

Name three (i) sulphates (ii) Chloride insoluble in water and- two (i) oxides (ii) carbonates soluble in water

Explain giving reasons why: (i) Mg(OH)_2 is sparingly soluble in water but highly soluble in ammonium chloride solution.
