Answer 1

Answer: (B)

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

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

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

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