Give an example for each of the following types of nuclear transmutation reactions: (p, α), (n, p), ( n, α) and (p, n).
Answers
Answer:
alpha decay
Equation 20.1: AZX→A−4Z−2X′+42αZAX→Z−2A−4X′+24α
beta decay
Equation 20.4: AZX→AZ+1X′+0−1βZAX→Z+1AX′+−10β
positron emission
Equation 20.7: AZX→AZ−1X′+0+1βZAX→Z−1AX′++10β
electron capture
Equation 20.10: AZX+0−1e→AZ−1X′+x-rayZAX+−10e→Z−1AX′+x-ray
gamma emission
Equation 20.15: AZX*→AZX+00γZAX*→ZAX+00γ
b) The carbon-oxygen double bond, C=O, is one of the really useful absorptions, found in the range 1680 - 1750 cm-1. Its position varies slightly depending on what sort of compound it is in. The other really useful bond is the O-H bond. This absorbs differently depending on its environment. It is easily recognised in an acid because it produces a very broad trough in the range 2500 - 3300 cm-1.
c) in 1,3 butadine has higher lmax. Because it has two chromaphor group.
