Here each questions contains statements given in two columnns which have to be matched. Statements in Column I are labelled as A, B C and D wheras the statements in Coloumn II are labelled as p,q,r and s. the answer to these questions are to be appropriately bubbled as illustrated below in the following example. if the correct matches are A-P, A-s,B-q, B-r, C p ,C-q and D-p, their correctly labelled 4 x 4 matrix should look the .
`{:(“Column I”,,”Column II”),(“(A) Sn”,,”(P) Highest density amongst group 14 elements “),(“(B) Pb”,,”(q) Lowest melting point amongst group 14 elements “),(“(C) Si”,,”(r) Lowest I.E. amongst group 14 elements”),(“(D) Ge”,,”(s) Semiconductor used in transistor”):}`
`{:(“Column I”,,”Column II”),(“(A) Sn”,,”(P) Highest density amongst group 14 elements “),(“(B) Pb”,,”(q) Lowest melting point amongst group 14 elements “),(“(C) Si”,,”(r) Lowest I.E. amongst group 14 elements”),(“(D) Ge”,,”(s) Semiconductor used in transistor”):}`
Correct Answer – A::B::C::D
Sn has the lowest mp and the lowest IE and Pb has highest density among carbon family members and both Si and Ge are used as semiconductors in transition.
