Answer 1

Answer:

Which of the following pairs is/are correctly matched?

Reaction Product

I. RX + AgCN RNC

II. RX + KCN RCN

O

III. RX + KNO₂ R – N

O

IV. RX + AgNO₂ R–O–N = O

(a) Only I (b) I and II

(c) III and IV

(d) I, II, III and IV

Answer 2

Reaction i and 2 are correct.

Explanation:

• The KCN is an ionic compound while AgCl is a covalent compound.

• So, KCN undergoes SN1 while AgCN undergoes SN2.

• So in case of AgCN, the substitution takes place from behind.

• Thus in case of AgCN, RNC is formed whole in KCN, RCN is formed.

• Similarly, in case of KNO2, its an ionic compound whole AgNO2 is a covalent compound.

• So in case of AgNO2, the alkyl molecule attack from behind and forms RNO2.

• While in case of KNO2, it forms RONO.
