Which of the following is not correctly matched?

An acyl chloride is hydrogenated over a catalyst of palladium on barium sulphate to form an aldehyde. This reaction is called:

$Pentan-3-one$ is not obtained from:

What is $X$ in the following reaction sequence?
$Toluene \xrightarrow[ii. HNO_3/H_2SO_4]{i. CrO_2Cl_2/CS_2, H_3O^+} X$

Identify the product $A$ in the following reaction:
$CH_3-CCl_2-CH_2-CH_3 + 2KOH_{(aq)} \xrightarrow{\Delta} A + 2KCl + H_2O$

$A$ man has been asked to synthesize the molecule shown in the image. He thought of preparing the molecule using an aldol condensation reaction. He found a few cyclic alkenes in his laboratory. He thought of performing an ozonolysis reaction on an alkene to produce a dicarbonyl compound,followed by an aldol reaction to prepare "$x$". Predict the suitable alkene that can lead to the formation of "$x$".
