Assertion: Amongest the halogens, fluori...

Assertion: Amongest the halogens, fluorine can oxidise the elements to the highest oxidation- state.
Reason: Due to small size of fluoride ion, it is difficult to oxidise fluoride ion to fluorine. Hence reverse reaction takes place more easily.

A

If both the assertion and reason are true and reason is the true explanation of the assertion.

B

If both the assertion and reason are ture but the reason is not the correct explanation of assertion

C

If the assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B

Due to high electronegativity and high heat of dissociation, fluorine oxidises the elements to their oxidation state.

    All the noble gases are colourless and tasteless monoatomic gases. In general, noble gases are least reactive and their inertness to chemical reactivity is attributed to the following reasons. Reactive and their inertness to chemical reactivity is attributed to the following reasons. (i)Except helium, all have completely filled ns^(2)np^(6) electronic configuration in their valence shells. (ii)All have high ionisation enthalpy and more positive electron gain enthalpy. However, a number of xenon compounds mainly with most electronegative elements like fluorine and oxygen have been synthesized under different conditions and fluorides of xenon have been used as an oxidising agent and a fluorinating agent in many of the chemical reactions Select the correct statement.

    Oxidation and reduction always occur simultaneously. These reactions which involve simultaneous oxidation and reduction are called redox reactions. Therefore, every redox reaction is made up of two half reactions. One half reaction represents oxidation and other half reaction represents the reduction. Oxidation and reduction of an atom, molecule or ion can also be defined in terms of electrons. The substance that gains electrons, is reduced to a lower oxidation state and acts as an oxidising agent. Similarly, the substance which loses electrons is oxidised to a higher oxidation state, and is called a reducing agent. In which of the following reactions hydrogen peroxide is acting as a reducing agent?
