Answer 1

The correct option is C (A) $\to$ r ; (B) $\to$ s ; (C) $\to$ p ; (D) $\to$ q

$TiC{l}_4-$ Ziegler-Natta catalyst

This catalyst is used in polythene production.

$PdC{l}_2$

This is used as an oxidizing agent in the Wake process to oxidize alkene to aldehyde.

$Pt{O}_2-$Adams catalyst

It is used in reduction reactions to convert nitro compounds to amines.

Cu is used in the preparation of $(C{H}_3{)}_{2}SiC{l}_2$.
