If P, Q, R and S are elements of 3rd period of p-block in modern perio – InterviewSolution

1.	If P, Q, R and S are elements of 3rd period of p-block in modern periodic table, among these one element is metal and rest are non-metals and their order of electronegativity is given as: P lt Q lt R lt S Q. Chloride compound of which element is hypovalent?
Answer» S Q R P Solution :According to the given information, ELEMENT P, belongs to 13th group and REST elements belongs to higher GROUPS, hence chloride to 13th group will only be hypovalent.
