Vedclass · Answer

(A) According to the $(n+l)$ rule,the energy of an orbital increases as the value of $(n+l)$ increases.If the $(n+l)$ values are the same,the orbital with the lower value of $n$ has lower energy.Calculating $(n+l)$ values for each:$(i)$ $n=4, l=1 \implies n+l=5$$(ii)$ $n=4, l=0 \implies n+l=4$$(iii)$ $n=3, l=2 \implies n+l=5$$(iv)$ $n=3, l=1 \implies n+l=4$Comparing the values:For $(n+l)=4$: $(iv)$ has $n=3$ and $(ii)$ has $n=4$. Thus,$iv For $(n+l)=5$: $(iii)$ has $n=3$ and $(i)$ has $n=4$. Thus,$iii Combining these,the order of increasing energy is: $iv < ii < iii < i$.

$(a)$ $i$ gene	$(i)$ $\beta$-galactosidase
$(b)$ $z$ gene	$(ii)$ Permease
$(c)$ $a$ gene	$(iii)$ Repressor
$(d)$ $y$ gene	$(iv)$ Transacetylase
