Answer:
Spectral patterns are unique to each element so they are used to identify the metal ions in the salts used in the flame tests.
The best set of reagents to achieve the ph-co2h => ph-come will be Br2, CH2N2.
A material or ingredient supplied to a system to trigger a chemical reaction or check to see whether one occurs is known as a reagent as well as an analytical reagent. Reactant refers to a substance that is consumed during a chemical reaction. The phrases reactant and reagent just aren't frequently used interchangeably.
Diazomethane reacts swiftly and extremely effectively, producing just N2 as a byproduct, making it an appealing methylating agent for carboxylic acids including phenols.
Therefore, the best set of reagents to achieve the ph-co2h => ph-come will be Br2, CH2N2.

Answer:
decrease
Explanation
During the co ordinate bond between the Carbonyl and The metal ,
The Carbonyl donates the sigma electrons and through the process of back bonding , it accepts the electrons in its pi star orbitals i.e. , the antibonding orbitals , thereby reduces the bond order and which in turns reduces the bond strength and , there fore ,
The IR stretching frequency for CO reduces .
