Question
Order of size of $$sp,s{p^2}$$ and $$s{p^3}$$ orbitals is
A.
$$s{p^3} < s{p^2} < sp$$
B.
$$sp < s{p^2} < s{p^3}$$
C.
$$s{p^2} < sp < s{p^3}$$
D.
$$s{p^2} < s{p^3} < sp$$
Answer :
$$sp < s{p^2} < s{p^3}$$
Solution :
The percentage of $$s$$ - character in $$s{p^3},s{p^2}$$ and $$sp$$ is 25%, 33% and 50% respectively. Order of size of orbitals is $$sp < s{p^2} < s{p^3}.$$
