Group 17 elements

________ has yellow, Cl2 has greenish yellow, Br2 has red and I2 has violet color.

________ doesnt have d- orbitals and hence cant expand its octet.

________ and Chlorine are gases, Bromine is a liquid and Iodine is a solid.

________ contain Iodine in their systems; various seaweeds contain iodine too.

It is a(n) ________ with pungent and suffocating odor.

________ have the least atomic size in their respective periods because they have maximum effective nuclear charge.

________ forms only two oxides OF2 and O2F2 among which only OF2 is thermally stable.

________ is used as a bleaching agent.

________ is a very good oxidizing agent used in the estimation of carbon monoxide.

________ for hydrogen decreases from fluorine to iodine.

________ is a radioactive element.

________ is liberated at anode in electrolysis of brine.

In ________, it is prepared by heating sodium chloride with concentrated sulphuric acid.

(________) Electrolytic process: Chlorine is obtained by the electrolysis of brine.

________ consists of chlorides, bromides, iodides of Sodium, Magnesium, Potassium and Calcium but as we know ________ majorly contains sodium chloride.

________, Cl2O, ClO2, Cl2O6 and Cl2O7 are highly reactive oxidizing agents and tend to.

It reacts with a(n) ________ and non- metals to form chlorides.

They are all volatile solids or liquids at 298K except _____ which is a gas.

(I) Deacons process: By ________ gas by atmospheric oxygen in the presence of CuCl2 (catalyst) at 723 K.

In general, ________ are more reactive than halogens (except fluorine)

________ have maximum negative electron gain enthalpy in their respective periods, this is because they need only one electron to achieve the noble gas configuration.

Oxidizing ability of the halogens decreases down the group with ________ being a powerful oxidizing agent.

________ behaves anomalously due to its small size, highest electronegativity, low bond dissociation enthalpy, and non availability of d orbitals in its valence shell.

________ can be prepared by heating manganese dioxide with concentrated HCl or by the action of HCl on potassium permanganate.

Due to high electronegativity and small size, ________ only one oxoacid, HOF known as fluoric (I) acid or hypofluorous acid.

________ is used in textile industries and in the manufacture of dyes, drugs, organic compounds, poisonous gases.

________ is present in form of insoluble fluorides and also in teeth and bones of animals.

________ are highly reactive non- metals.

I> Br> Cl> F

F> Cl> Br> I

Cl> F> Br> I this is because Fluorine has small size and has more interelectronic repulsions so the incoming electron doesnt face much attraction

F> Cl> Br> I> At

Cl-Cl> Br-Br> I-I

HF < HCl < HBr < HI

H-F > H-Cl > H-Br > H-I

H-F > H-Cl > H-Br > H-I

HF < HCl < HBr < HI

O2F2 oxidizes plutonium to PuF6 and the reaction is used in removing plutonium as PuF6 from spent nuclear fuel

I> Cl> Br

MF > MCl > MBr > MI

By oxidation of hydrogen chloride gas by atmospheric oxygen in the presence of CuCl2 (catalyst) at 723 K

Chlorine is obtained by the electrolysis of brine

Ca(OCl)2.CaCl2.Ca(OH)2.2H2O

The word Tear gas can be heard in most of the military themed movies but do you know its chemical formula
