Draw the bridged bromonium ion that is formed as an intermediate during the bromination of this alkene. Include hydrogen atoms, nonbonding electrons, and formal charge(s) in your structure. The starting alkene is a 4 carbon chain with a double bond between carbons 2 and 3. The substituents on the alkene are on opposite sides of the alkene. This reacts with B r 2 to give the intermediate ion.

Answer:

See explanation and image attached

Step-by-step explanation:

The reaction of bromine molecule with an alkene passes through a bridged intermediate known as the brominium ion.

It is a cyclic intermediate that contains a positively charged bromine ion as i have shown in the image attached.

The brominium ion is first formed during the bromininaton of alkenes.
