Molecules which have polar nature are capable to form hydrogen bond are generally soluble in water. In sucrose and glucose hydroxyl groups are present, which is polar in nature. Therefore, they are involved in intermolecular hydrogen bonding with water molecules, so these compounds are readily soluble in water. On other hand benzene and cyclohexane are hydrocarbons. They do not have any polar group so they cannot make hydrogen bonds with water.
The melting points and solubility of water of amino acids are generally higher than that of the corresponding halo acids. Explain.
What products would be formed when a nucleotide from DNA containing thymine is hydrolysed?
When RNA is hydrolysed, there is no relationship among the quantities of different bases obtained. What does this fact suggest about the structure of RNA?
