Which of the following gives two isomers of $3^o$ alcohol,when treated with phenyl magnesium bromide?

What is Schiff's reagent?

Identify compound $B$ in the following reaction sequence:
Cyclopentanone $+ H_2NOH$ $\xrightarrow{pH = 4.5, \Delta} (A)$ $\xrightarrow{H^+ / \Delta} (B)$

In the reaction scheme shown below,$Q$,$R$,and $S$ are the major products. Identify the correct structure of the products from the given options:
$(P)$ + Succinic anhydride $\xrightarrow{AlCl_3}$ $Q$
$Q$ $\xrightarrow[H_3PO_4]{Zn-Hg/HCl}$ $R$
$R$ $\xrightarrow[(ii) H_3O^+]{(i) CH_3MgBr, (iii) H_2SO_4/\Delta}$ $S$
$(A)$ $S$ is [Structure $A$]
$(B)$ $Q$ is [Structure $B$]
$(C)$ $R$ is [Structure $C$]
$(D)$ $S$ is [Structure $D$]

Match the following reagents with the products obtained when they react with a ketone.

List-$I$	List-$II$
$A. \ C_6H_5NHNH_2$	$I. \ \text{Schiff base}$
$B. \ NH_2OH$	$II. \ \text{Hydrazone}$
$C. \ C_6H_5NH_2$	$III. \ \text{Oxime}$
	$IV. \ \text{Phenyl hydrazone}$

Correct answer is:

Match the following lists:

List-$I$	List-$II$
$A$. Grignard reagent	$1$. $H_2 / Pd-BaSO_4$
$B$. Clemmensen reduction	$2$. $N_2H_4 / KOH / (CH_2OH)_2$
$C$. Rosenmund reduction	$3$. $CH_3MgX$
$D$. Wolff-Kishner reduction	$4$. $Zn-Hg / \text{conc. } HCl$
	$5$. $H_2 / Ni$
