316617 The halogen which is solid at room temperature is

1 \(\mathrm{I}_{2}\)
2 \(\mathrm{Br}_{2}\)
3 \(\mathrm{Cl}_{2}\)

CHXI11:THE P-BLOCK ELEMENTS

316618 Assertion :
All the halogens are coloured.
Reason :
Halogen molecules absorb some wavelengths of visible light and the electrons are promoted to higher energy molecular orbitals.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
