Propose a mechanism for each reaction, showing explicitly

QUESTION:

Propose a mechanism for each reaction, showing explicitly how the observed mixtures of products are formed

(a) 3 -methylbut-2-en-1-ol + \(\mathrm{HBr} \rightarrow 1 \) -bromo-3-methylbut-2-ene  -bromo-3-methylbut-1-ene

(b) 2 -methylbut-3-en-2-ol + \(\mathrm{HBr} \rightarrow 1\) -bromo-3-methylbut-2-ene  -bromo-3-methylbut-1-ene

(c) cyclopenta- 1,3 -diene + \(\mathrm{Br}_{2} \rightarrow 3,4\) -dibromocyclopent-1-ene  -dibromocyclopent-1-ene

(d) 1 -chlorobut-2-ene + \(\mathrm{AgNO}_{3}, \mathrm{H}_{2} \mathrm{O} \rightarrow\) but-2-en-1-ol  but- 3 -en-2-ol

(e) 3 -chlorobut-1-ene + \(\mathrm{AgNO}_{3}, \mathrm{H}_{2} \mathrm{O} \rightarrow\) but-2-en-1-ol  but- 3 -en-2-ol
