27. How can you get CH2BrCH2OH from CH2CH2? Electrophilic addition will yield CH2BrCH2Br. To get the CH2BrCH2OH, you'll need an additional step - nucleophilic substitution. A is wrong; both products are not obtained by electrophilic addition.Do you know how to do Qs (27),(26) and the (30)?

30. HCN won't reaction with the C=C double bond in the compound C, it'll only react with the CHO group. So only 1 mole of HCN will react with the compound in C.
