As the positive charge decreases, the bond between nitrogen and oxygen becomes stronger. So, the correct order of the bond energies is NO⁺ > NO > NO^-.

Carbonyl compounds are reduced to corresponding alkanes with (Zn+ conc HCl). It is called Clemmensen reduction.

Diastereomerism occurs when two or more stereoisomers of a compound have different configurations at one or more (but not all) of the equivalent stereocentres and are not mirror images of each other. Thus,

The given amino acid is glycine. It is a neutral amino acid that does not react with both acid and base. 

n order for PCl₅ to be formed, there must be five bonds, and to form five bonds, phosphorus must have five unpaired valence electrons. Phosphorus and nitrogen both have five valence electrons.

In order to have five unpaired electrons in P, we can imagine an electron being promoted from the 3s to the 3d sub-level. This will give 5 unpaired electrons, and the ability to form PCl₅. We can also relate this to the use of the d orbitals in phosphorus with sp³d hybridisation.

But for nitrogen, there are no 2d orbitals to promote a 2s electron into and no way to come up with five unpaired electrons. Therefore, NCl₅ does not exist. 

Development of a photographic plate involves the use of a reducing agent.

Pt(II) is always square planar and so there are only two isomers the cis-(Cl)₂Pt(NH₃)₂ and trans isomers (Cl)(H₃N)Pt(NH₃)(Cl).

The cis isomer is the famous anticancer drug cis platin 

Formation of violet colour is due to the presence of Na₃[Fe(CN)₅NOSNa]

Straight chain olefins have the highest knocking.

Meta product is the major product in this reaction.Benzoic acid is produced commercially by partial oxidation of toluene with oxygen. The process is catalyzed by cobalt or manganese naphthenates. The process uses abundant materials, and proceeds in high yield.
