Two different bromonium ions are formed because br2 can add to the double bond either from the top of the plane or from the bottomtwo different bromonium ions are formed because {\rm br_2} can add to the double bond blank of the plane defined by the double bond, and the two bromonium ions are formed in equal amounts. of the plane defined by the double bond, and the two bromonium ions are formed in equal amounts.

a) true

b) false

 True

Explanation:  When the alkene is being treated with Br2 in a aprotic solvent, the Br2 will get add on the alkene forming the bromonium ion. This intermediate can be formed from either of the side depending on the substituents of the alkene.

Thus, the two bromonium ions are formed in equal amounts. The alkene is acting as the elctrophile and the Br2 will act as the nucelophile as its antibonding orbital is higher in energy.

no but i do not usually comment or use my voice that much when it comes to social media

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
