Correct answer
D. a-q, b-s, c-p, d-r
Step-by-step solution
(a) 1-Butene ( ) 2-Butanol This conversion involves hydroboration-oxidation, which requires BH3/THF (q) followed by CH 3 COOH and ( H ₂ O ₂ ). (b) 1-Butene ( ) 1-Butanol This conversion involves electrophilic addition of HBr followed by hydrolysis, which requires ( HBr / H ₂ O ₂ ) (s) and aq KOH. (c) Propene ( ) Propane This conversion involves hydrogenation, which requires ( BH ₃ / THF ( p ) ) or more commonly ( H ₂ / Pd ) or ( H ₂ / Pt ). (d) 2-Bromopropane ( ) 1-Bromo propane This conversion involves dehydrohalo
