NTA JEE Mains 23rd Jan 2025 Shift 2

Given below are two statements about X-ray spectra of elements : Statement (I) : A plot of $$\sqrt{v}$$($$\upsilon$$ = frequency of -rays emitted) vs atomic mass is a straight line. Statement (II) : A plot of $$\upsilon(\upsilon$$ = frequency of -rays emitted) vs atomic number is a straight line. In the light of the above statements, choose the correct answer from the options given below :

Identify A,B and C in the given below reaction sequence 

Given below are two statements : Statement (I) : The boiling points of alcohols and phenols increase with increase in the number of C-atoms. Statement (II) : The boiling points of alcohols and phenols are higher in comparison to other class of compounds such as ethers, haloalkanes. In the light of the above statements, choose the correct answer from the options given below :

Consider a binary solution of two volatile liquid components 1 and 2.$$x_{1}$$ and $$y_{1}$$ are the mole fractions of component 1 in liquid and vapour phase, respectively. The slope and intercept of the linear plot of $$\frac{1}{x_{1}}$$ vs $$\frac{1}{y_{1}}$$ are given respectively as:
