Answer 1

Answer: (B)

$( a \rightarrow s )$ Write the structure of propane dithioic acid
diagram. The structure of G.R. would be EtMgBr

$( b \rightarrow r )$ Write the structure of propyl sulphonicacid

$( c \rightarrow s )$ Write the structure of ethyl mercaptan(Et - SH). The structure of G.R. would be EtMgBR

$( d \rightarrow p )$ It is a method of preparation of ether
