Consider the following reaction :
A + alkali $$\to$$ B (Major Product)
If B is an oxoacid of phosphorus with no P-H bond, then A is :
Polar stratospheric clouds facilitate the formation of :
Given below are two statements :
Statement I : In 'Lassaigne's Test', when both nitrogen and sulphur are present in an organic compound, sodium thiocyanate is formed.
Statement II : If both nitrogen and sulphur are present in an organic compound, then the excess of sodium used in sodium fusion will decompose the sodium thiocyanate formed to give NaCN and Na2S.
In the light of the above statements, choose the most appropriate answer from the options given below :
(C7H5O2)2 $$\buildrel {hv} \over \longrightarrow $$ [X] $$\to$$ 2C6H5 + 2CO2
Consider the above reaction and identify the intermediate 'X'
