Answer #1

Addition of H2O to a double bond (alkenes) is occuring :

1. In the presence of Sulphuric acid (H2SO4).

The initial protonation can occur on either face of the double bond and addition of water can occur on either side of the carbocation, so there is no stereoselectivity in this reaction (form a mix of stereoisomers)

2. In the presence of Borane(BH3) and Hydrogen peroxide(H2O2) , Sodium hydroxide (NaOH).

This is syn addition due to the 4-centered transition state, but it can happen on either face of the double bond, so a mixture of enantiomers forms if there are no other stereocenters in the molecule

Hello I have a question about organic chemistry 1 lab. When doing chemical tests the Br2 in CCl4. Shows a positive result for alkenes and alkynes? And negative test results mean a alkene and/or arene? I’m told in lab that we do not have potassium permanganate so we cannot use it. The second test that were told to preform if nothing else is shown on the IR is a halide test. I hope this makes sense. I’m just confused about...
