An organic compound answers Molisch's test as well as Benedict's test. But it does not answer Scliwanoffs test. Most probably, it is

• sucrose

• protein

• fructose

• maltose

In qualitative analysis, in order to detect second group basic radical, H₂S gas is passed in the presence of dilute HCl to

• increase the dissociation of H₂S

• decrease the dissociation of salt solution

• decrease the dissociation of H₂S

• increase the dissociation of salt solution

Pick out the unsaturated fatty acid from the following
