Identify B formed in the reaction.

$$\mathrm{Cl}-\left(\mathrm{CH}_2\right)_4-\mathrm{Cl} \xrightarrow{\text { excess } \mathrm{NH}_3} \mathrm{~A} \xrightarrow{\mathrm{NaOH}} \mathrm{B}+\mathrm{H}_2 \mathrm{O}+\mathrm{NaCl}$$

Identify from the following species in which $$\mathrm{d}^2 \mathrm{sp}^3$$ hybridization is shown by central atom :

Phenolic group can be identified by a positive:

Match List - I with List - II.

	List - I (Reaction)		List - II (Reagent(s))
(A)		(I)	$$\mathrm{Na_2Cr_2O_7,H_2SO_4}$$
(B)		(II)	(i) $$\mathrm(NaOH)$$, (ii) $$\mathrm{CH_3Cl}$$
(C)		(III)	(i) $$\mathrm{NaOH,CHCl_3}$$, (ii) $$\mathrm{NaOH}$$, (iii) $$\mathrm{HCl}$$
(D)		(IV)	(i) $$\mathrm{NaOH}$$, (ii) $$\mathrm{CO_2}$$, (iii) $$\mathrm{HCl}$$
