Homologous compound have same:

The hybridization of central atoms of compounds A, B, C and D are sp^(3)d, sp^(3), sp^(2) and sp respectively. If compounds A and D have same shape like I_(3)^(-) and compounds B and C have same shape like water structure. Then calculate value of "P+Q+R+S", where P, Q, R, and S are number of lone pairs on central atoms of compounds A, B, C and D respectively.

Consider the following compounds If 'p' is the number of compounds having more enol content than III, 'q' is the number of compounds having enolic form more stable than that of IV and 'r' is the number of compounds having percentage of enolic form more than the corresponding keto form, find p+q+r . Fill your answer as sum of digits (excluding decimal places) till you get the single digit answer.
