Select correct description of a bromonium ion. a. a cationic molecule with the general formula R − Br + b. a cationic molecule with the general formula R − Br − Br + c. an ion with the formula Br + 2 d. a cationic molecule containing a three‑membered ring with the general formula R − Br + − R ′ an ion with the formula Br − 3

Explanation:

A bromonium ion is a positive ion (cation) formed by a bromine atom attached to two carbon atoms.

The positive charge is on the bromine atom.

Regularly, a Br atom has 7 valence electrons. That is when Br is neutral.

When a Br atom forms a covalent bond with a C atom, they share one electron each and thus Br completes its octet: 8 electrons.

When a Br atom combine with two different C atoms, now Br is sharing one additional electron, which leaves it with and excess of positive charge. That is why the Br atom in the bromonium ion has a positive charge, making it a cationic species.

The two C atoms, bonded to each other and to the Br⁺ form a cyclic species of this kind:

   − C −    C −

       \       /

         Br⁺

Hence, it is a ring.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
