What factors govern the position of an IR absorption peak? Select one or more correct answers.

Chemistry
1 answer:
____ [38]4 years ago
5 0

Answer:

The factors that govern the position of an IR absorption peak are:

(A) strength of the bond

(C) masses of the atoms involved in the bond

(D) the type of vibration being observed

Explanation:

In infrared spectroscopy the molecules absorb the frequencies that are characteristic of their structure. These absorptions occur at resonance frequencies, that is, the frequency of the absorbed radiation coincides with the frequency of vibration. The energies are affected by the shape of molecular potential energy surfaces, the masses of atoms and the associated vibronic coupling. The resonance frequencies are also related to the strength of the bond and the mass of the atoms at each end of it. Therefore, the frequency of vibrations is associated with a particular normal movement mode and a particular type of link.

igor_vitrenko [27]
Answer:
Case 1:
            X  =  Any element from Group I
            
                       i)    H
                       ii)   Li
                       iii)  Na
                       iv)  K
                       v)   Rb
                       vi)  Cs

            Y  =  1

Case 2:
            X  =  Any element from Group II
            
                       i)    Be
                       ii)   Mg
                       iii)  Ca
                       iv)  Sr
                       v)   Ba
                       vi)  Ra

            Y  =  2

Case 3:
            X  =  Any element from Group III
            
                       i)    B
                       ii)   Al
                       iii)  Ga
                       iv)  In
                       v)   Ti

            Y  =  3

Explanation:
                   The general formula given is as follow,

                                                    XCly

So, if X has +1 oxidation state, then it will require only one Cl atom with oxidation number -1 to form a neutral compound, therefore, y = 1.

If X has +2 oxidation state, then it will require two Cl atoms with oxidation number -1 to form a neutral compound, therefore, y = 2.

If X has +3 oxidation state, then it will require three Cl atoms with oxidation number -1 to form a neutral compound, therefore, y = 3.
