• B. A -(s), B -(q,r), C - (p,q,r), D - (q)
• C. A -(p,q,r), B -(r,s), C - (q,r), D - (s)
• D. A -(q), B -(q,r), C - (r,s), D - (p,q,r)

Answer 1

Answer: (A)

$( a \rightarrow q , r )$ internal alkynes do not react with Tollens reagent, but with $NaNH _2$ isomerisation takes place to give terminal alkynes

$(b \rightarrow p, q, r)$ Terminal alkynes react with both Tollens reagent and $NaNH _2$ to undergo hydrogenation

$( c \rightarrow s )( d \rightarrow s )$ Alkenes do not react with Tollens reagent or $NaNH _2$ or $D _2+ Ni _2 B$
