5a. \(CH_3CH_2CH_2Br\underrightarrow{KOH/ancol}C_3H_6\left(A\right)+HBr\)
\(C_3H_6+Br_2\rightarrow C_3H_6Br_2\left(B\right)\)
\(C_3H_6Br_2+Zn\underrightarrow{t^o}C_3H_6\left(C\right)+ZnBr_2\)
\(C_3H_6+H_2O\underrightarrow{HgSO_4/H_2SO_4}C_3H_7OH\left(D\right)\)
b. \(CH_3CH_2CH=CH_2+Br_2\rightarrow CH_3CH_2CHBrCH_2Br\left(A\right)\)
\(C_4H_8Br_2\underrightarrow{2KOH/ancol}C_4H_6+2HBr\)
