PCl5 is possible but NCl5 does not exist :
(a) in N, d-sub-shell is absent
(b) ionization energy of N is very high
(c) it does not like Cl
(d) None of these
(a) NCl5 in not possible because N does not contain d-orbitals. Only nitrogen has a tendency to form pπ – pπ multiple bonds. Other forms dπ –pπ multiple bonds easily
Skin colour is controlled by three genes; A,B,C dominant genes and a,b,c the recessive genes ; the effect of each type of allele is addictive ; more the dominant allele,...
