 & III.\,\,C{{a}_{2}}Pb{{O}_{4}}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,Y.\,\,road\,signs\,and\,markings \\
 & IV.\,\,PbCr{{O}_{4}}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,Z.\,red\,lead \\
\end{align}$
A.I-Y, II-Z, III-X, IV-W
B. I-X, II-W, III-Y, IV-Z
C. I-Z, II-W, III-X, IV-Y
D. I-X, II-Y, III-W, IV-Z

Answer 1

Hint: Lead is an element of group 14 carbon family with atomic number 82. Lead is an important element that has a wide range of applications. Its important compounds include its oxides, carbonates, chromates, etc. These are used for various purposes like its form plumbate used as rust proofing sheet.

Complete answer:
Lead can be used in various forms given in column A. We have to match these compounds of lead with the properties of column B.
I.Given is $P{{b}_{3}}{{O}_{4}}$ which is called trilead tetraoxide. This is also known as red lead due to its red color. So, I am matched with Z, which is red lead.
II. ${{\left( PbC{{O}_{3}} \right)}_{2}}Pb{{(OH)}_{2}}$ is called as basic lead carbonate. Due to the presence of carbonate it is white in color and termed as white lead. So, II is matched with W.
III. $C{{a}_{2}}Pb{{O}_{4}}$ is called calcium plumbate, this is used as a rust proofing sheet. So, III is matched with X.
IV. $PbCr{{O}_{4}}$ is lead chromate that is yellow in color and used as paint in road signs and markings. So, IV is matched with Y.

Hence, the correct order of the matching sequence is I-Z, II-W, III-X, IV-Y. So, option C is correct.

Note:
White lead is widely used in the making of plasters and in the making of pottery. The white lead mixture is basic as it contains carbonates. Tri lead tetroxide is also known as lead oxide. It is formed by the heating of PbO. It is used as a common adulterant in turmeric powder. Most common use is that it is applied by married women as sindoor.
