Answer to Question #86783 in Inorganic Chemistry for Shubham

Question

Questn1:::::::1s,2px,3dxy
Classify as gerade or ungerade?
Questn2:::::give an example each for nuclear transmutation reactions of the type (alpha,gamma),(alpha,p),(p-gamma),()

Answer 1

(i) Orbitals which are left unchanged by the operation of inversion are gerade, while those which undergo a change in sign are ungerade. 1s and 3dxy are left unchaned by the operation of inversion, they are gerade. 2px undego a change in sign, this orbital is ungerade.

(ii)

(alpha, gamma):

$$_{16}^{32} S + _2^4 He \rightarrow _{18}^{36} Ar + _0^0 \gamma$$

(alpha, p):

$$_{19}^{39}K + _2^4He \rightarrow _{20}^{42}Ca + _1^1p$$

(p, gamma):

$$_6^{12}C + _1^1p \rightarrow _7^{13}N + _0^0 \gamma$$
