Assertion: Glucose reacts with hydroxylamine to form an oxime and also adds a molecule of hydrogen cyanide to give cyanohydrin.

Reason: The carbonyl group is present in the open chain structure of glucose.


Due to the presence of (-C=O) group present in the open chain structure of glucose molecule, it can lose a water molecule (when it reacts with other molecules) thereby forming various compounds. In hydroxylamine, the H2 part in it combines with the (-C=O) part so that an oxime (C=NOH) can be created by the loss of a water molecule.



Also, ketones or aldehydes form cyanohydrins, when they react with HCN.

The incorrect statement about LDP is:


 16

Assertion: The two strands in double strand helix structure of DNA are complementary to each other

Reason: Disulphide bonds are formed between specific pairs of bases


 18

Assertion: The acidic strength of halogen acids varies in the order HF>HCl>HBr>HI

Reason: The bond dissociation enthalpy of halogen acids decreases in the order HF>HCl>HBr>HI


 19

Assertion: C2H5OH is a weaker base than phenol but is a stronger nucleophile than phenol. (1)

Reason: In phenol the lone pair of electrons on oxygen is withdrawn towards the ring due to resonance.
