The number of a and β particles formed during the various stages of transformations during the decay series of 2 4 7 Bk giving 2 0 7 Pb as its final product needs to be determined. Concept introduction: The unstable atomic nucleus that does not have the same number of protons and neutrons will transform to smaller stable units releasing radiations like alpha, beta and gamma. Alpha particles have two neutrons and two protons while beta decay will occur causing conversion of proton to neutron or neutron to protons. But in gamma ray emission, there is no loss or gain of electrons or neutrons.

Give the product of the bimolecular elimination from each of the isomeric halogenated compounds. Reaction A Reaction B. КОВ CH₂ HotBu +B+ ко HOIBU +Br+ Templates More QQQ Select Cv Templates More Cras QQQ One of these compounds undergoes elimination 50x faster than the other. Which one and why? Reaction A because the conformation needed for elimination places the phenyl groups and to each other Reaction A because the conformation needed for elimination places the phenyl groups gauche to each other. ◇ Reaction B because the conformation needed for elimination places the phenyl groups gach to each other. Reaction B because the conformation needed for elimination places the phenyl groups anti to each other.
