Explain The bromonium ion
The bromonium ion derived from the reaction of cyclopentene with bromine undergoes backside substitution by water to give the trans-bromohydrin, which is chiral. Because the starting materials are achiral, the chiral product is obtained as a racemate.

It can be because these group tend to decrease the electron density when attached to a benzene or other ring structure preferentially at ortho and pera position.
As the electron move away from the nucleus,its potential energy
The first ionization potentials for Na, K, and Rb are 5.138, 4.341, and 4.166 eV, respectively. Assume that the energy level of the outer electron can be represented by a hydrogenl
