Explanation
(d) Reduction of Mn in KMnO4 and production of Cl2.
Bond dissociation energy decreases in the order Cl2 > Br2 > F2.
Hybridization in ICl7 is sp3d3 giving a pentagonal bipyramidal shape.
Acidity decreases as the electronegativity of the central halogendecreases from Cl to I in HXO.
As the oxidation number of X in HXOn increases from HClO to HClO4,the acidity also increases.
Strongest bond is present in Cl2.
Bond energies decreases in the order Cl2 > Br2 > I2.
I2 cannot oxidize Br‒ to Br2
Bond energy of F2 is less than that of Cl2.
HF is a weaker acid than HCl.
HCl gas in presence of moisture in air forms droplets of liquid solution in the form of cloudy smoke.
Anhydrous Mg (ClO4)2 is known as ‘anhydrone’ which is used as adesiccant.
Reducing power increases in the order as H-X bond length increasesfrom HF to HI. HF < HCl < HBr < HI.
The Order is due to inert pair effect
Al2O3 is an amphoteric Oxide.
Liquified Ga expand on solidification Ga is less electropositive in nature. It has the weak metallic bond. so it expand on solidification
B4C is the hardest substance along with diamond
Except B(OH)3 all other hydroxides are of metallic hydroxide having the basic nature B(OH)3 are the hydroxides of non metal showing the acidic nature
Boro form different hydrides of general formula BnHn + 4 and BnHn+6 but BH3 is unknown
Alumina is amphoteric oxide which reacts with acid as well as base
Due to formation of chelated complex, the reaction moves in forword direction
