The species in which the N atom is a state of sp hybridization is:
Which of the following atoms has the highest first ionization energy?
The non-metal that does not exhibit positive oxidation state is:
The group of molecules having identical shape is:
Assertion: Among the carbon allotropes, diamond is an insulator, whereas, graphite is a good conductor of electricity. Reason: Hybridization of carbon in diamond and graphite are $s{p}^{3}$ and $s{p}^{2}$ respectively.
The bond angle H-X-H is the greatest in the compound :
The following statements concern elements in the periodic table. Which of the following is true?
The reaction of zinc with dilute and concentrated nitric acid, respectively, produces:
Which of the following is an example of homoleptic complex?
The pair having the same magnetic moment is: $[At. No. :Cr=24, Mn=25, Fe=26, Co=27]$
Which one of the following complexes shows optical isomerism? (en=ethylendiamine)
Which one of the following complexes will consume more equivalents of aqueous solution of ${\mathrm{AgNO}}_{3}$ ?
Which of the following are the transition metal ions responsible for colour in ruby and emerald respectively?
Identify the correct trend given below: (Atomic No. = Ti : 22, Cr : 24 and Mo : 42)
Identify the reaction which does not liberate hydrogen
Which one of the following species is stable in aqueous solution?
The correct statement on the isomerism associated with the following complex ions. (a) ${[Ni{({H}_{2}O)}_{5}N{H}_{3}]}^{2+}$ (b)${[Ni{({H}_{2}O)}_{4}{(N{H}_{3})}_{2}]}^{2+}$ and (c) ${[Ni{({H}_{2}O)}_{3}{(N{H}_{3})}_{3}]}^{2+}$ is:
After understanding the assertion and reason, choose the correct option. Assertion: In the bonding molecular orbital (MO) of ${\text{H}}_{2} ,$ electron density is increased between the nuclei. Reason: The bonding MO is ${\text{ψ}}_{\text{A}}+{\text{ψ}}_{\text{B}}$ , which shows destructive interference of the combining electron waves.
