NTA JEE Main 27th June 2022 Shift 1 - Question 37
L-isomer of a compound 'A'($$C_4H_8O_4$$) gives a positive test with $$[Ag(NH_3)_2]^+$$. Treatment of 'A' with acetic anhydride yields triacetate derivative. Compound 'A' produces an optically active compound (B) and an optically inactive compound (C) on treatment with bromine water and $$HNO_3$$ respectively. Compound (A) is :
NTA JEE Main 27th June 2022 Shift 1 - Question 38
Given below are two Statements :
Statement I : Classical smog occurs in cool humid climate. It is a reducing mixture of smoke, fog and sulphur dioxide.
Statement II : Photochemical smog has components, ozone, nitric oxide, acrolein, formaldehyde, PAN etc.
In the light of the above statements, choose the most appropriate answer from the options given below.
NTA JEE Main 27th June 2022 Shift 1 - Question 39
Given below are two statements : one is labelled as Assertion and the other is labelled as Reason.
Assertion: At $$10°$$C, the density of a $$5$$ M solution of KCl [atomic masses of K & Cl are $$39$$ & $$35.5$$ g mol$$^{-1}$$ respectively], is 'x' g mL$$^{-1}$$. The solution is cooled to $$-21°$$C. The molality of the solution will remain unchanged.
Reason: The molality of a solution does not change with temperature as mass remains unaffected with temperature.
In the light of the above statements, choose the most appropriate answer from the options given below.
