Assertion (A): Tungsten has a very high melting point. Reason (R): Tungsten is a covalent compound. Choose the correct option about A and R.

1. Both (A) and (R) are true and (R) is the correct explanation of (A)
2. Both (A) and (R) are true but (R) is not the correct explanation of (A)
3. (A) is true but (R) is false
4. (A) is false and (R) is true

Correct answer: (A) is true but (R) is false

Solution

Tungsten does have a very high melting point (about 3422 C), so A is true; but it is a metallic element, not a covalent compound, so R is false.
