Answer:
See explanation
Explanation:
The reaction with and will add <u>two "OH" groups to the molecule.</u> In the reaction (figure 1) we can see the different structures for the alkenes. In the <u>Z alkene (cis)</u> we have the 2 methyl groups on the same side. In the <u>E alkene (trans)</u> the 2 methyl groups are placed on opposite sides. In the products, all the "<u>OH" groups are placed at the top</u>. This indicates that the addition of the hydroxyl groups is "syn". In the syn reactions, all the groups are bonded on the <u>same side</u> therefore we will have a <u>stereospecific reaction</u>.
I hope it helps!
