A biosphere is the sum of all the ecosystems established on planet Earth.

An ecosystem is an area in which the plants and animals all interact to create a living environment. Therefore ecosystem is a smaller unit of earth, all ecosystems together form the earth.

Infrared spectroscopy involves the interaction of infrared radiation with matter. It is used by chemists to determine functional groups in molecules. IR Spectroscopy measures the vibrations of atoms, and based on this it is possible to determine the functional groups.

Here in the given spectrum, there is no alcohol stretch present in the spectrum. There is no vinyl bending present in the spectrum.
 

Hence, both options B and C are compounds that are not matching with IR spectrum. 1, 5 – Hexadiene is the compound matches the IR Spectrum.

63.5% of 8924.2 +? % of 5324.4 = 6827.5862

=> 63.5% of 8925 + ? % of 5325 = 6830

=> 6830 ~= 5320 + ?(5325)/100

=> ? ~= 22

 Given A = log321875 and B = log2432187

B = log352187 = log321875

=> A

Therefore, A = B

 $$\begin{gathered} = log 33 + log 23+ log 103log10×3×22 \\ \end{gathered}$$
