The most suitable reagent for the conversion of $R-CH_2-OH \rightarrow R-CHO$ is:

What is the product formed when side chain chlorination of toluene is carried out followed by acid hydrolysis at $373 \ K$?

Identify the product '$Y$' in the following reaction: $\text{Benzonitrile} \xrightarrow{C_6H_5MgBr/\text{dry ether}} X \xrightarrow{H_3O^+} Y + MgBr(OH) + NH_3$

Chromyl chloride converts a methyl group to a chromium complex,which on acid hydrolysis gives the corresponding aldehyde. This reaction is called:

In the following reaction sequence,identify the compound $Z$ if the starting material is toluene $(C_6H_5CH_3)$:
$C_6H_5CH_3 \xrightarrow{CrO_2Cl_2 / CS_2, H_3O^+} Z$

Consider the following reactions:
$C_2H_2 + H_2O \xrightarrow[333 \ K]{Hg^{2+} / H^{+}} [X] \stackrel{\text{Isomerisation}}{\rightleftharpoons} Y$
$Y$ cannot be obtained from which of the following reactions?
