JEE Advanced Chemistry Mock Test – 1

Fluorine is the most electronegative element on the periodic table.

$\text{PCl}_5$ has a trigonal bipyramidal geometry in the gaseous phase.

Sodium chloride ($\text{NaCl}$) is a strong electrolyte as it completely dissociates in water.

$\text{Na}^+$ has the same number of electrons as neon, making it isoelectronic.

The coordination number of iron in $\text{[Fe(CN)}_6\text{]}^{3-}$ is 6, due to the six cyanide ligands attached.

Acetic acid ($\text{CH}_3\text{COOH}$) is an example of a carboxylic acid.

The bond order of $\text{O}_2^+$ is 1.5, calculated from molecular orbital theory.

Carbon dioxide ($\text{CO}_2$) is an acidic oxide that reacts with water to form carbonic acid.

$\text{CaSO}_4\cdot2\text{H}_2\text{O}$ is commonly known as gypsum.

Acetylene ($\text{C}_2\text{H}_2$) contains a triple bond between the carbon atoms.

Cesium has the largest atomic radius among the given options.

Hydrofluoric acid ($\text{HF}$) is a weak acid compared to hydrochloric, sulfuric, and nitric acids.

Ammonia ($\text{NH}_3$) is a monodentate ligand, binding to a metal through a single donor atom.

$\text{NO}$ has an unpaired electron, making it paramagnetic.

Hydrogen cyanide ($\text{HCN}$) has a linear structure due to its $\text{sp}$ hybridization.

$\text{Zn}^{2+}$ is diamagnetic as all electrons are paired.

Saponification involves the reaction of a fat with sodium hydroxide to form soap.

Chlorine has the highest electron affinity among the halogens.

Nickel(II) complex $\text{[Ni(CN)}_4\text{]}^{2-}$ has a square planar geometry.

The oxidation state of chromium in potassium dichromate is $+6$.
