Assertion: Tungsten has very high melting point.
Reason: Tungsten is a covalent compound.

Options

A. If both assetion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are ture but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer

C

Explanation

Assertion: The maxima at about the middle of each series indicate the one upaired strong interatomic interaction. In general, greater the number of valence electrons, stronger number of unparied electrons and therefore, these are very hared metals have maximum enthaopies of atomization. so tungsten has very high melting point.
Reason: It is not a covalent compound but is a metal, i.e., an element.
