Question

Identify the correct matching from the following options:

Answer the following by appropriately matching the list based on the information given in the paragraph.

Some reactions/processes are given in List-I and some reaction intermediates (which can be formed in the reaction given in List - I) are given in List-II:

LIST–I:
(I) To determine the sequence of amino acids in a polypeptide chain by using 2,4-Dinitrofluorobenzene
(II) Cl-cyclohexanone with NaOEt/EtOH forming cyclopentane with C-OEt and double-bonded O substituent
(III) Cyclohexanone oxime -> AlCl3 -> Caprolactam
(IV) Biphenyl with triangular bridge -> hv -> Phenanthrene

LIST–II:
(P) Carbocation
(Q) Carbanion
(R) Free radical
(S) Benzyne
(T) Nitrene
(U) Carbene

Correct answer: B. An adiabatic process implies q = 0, and with volume not changing we have V 0   ; therefore, W = 0 and thus U 0   . The constant ‘U’ and ‘V’ allows us to apply the strict entropy spontaneity test; if S 0   the process is spontaneous. Since, we are given that S is +ve, so the process must be spontaneous.    G H T S Here, H U 0,    S ve  So, G  must be negative.
