Assertion (A) : Cyclohexane is the most stable cycloalkane.
Reason (R) : Cyclopropane and cyclobutane are less stable due to angle starin and torsional strain.
The correct answer is-
Both (A) and (R) are true but (R) is not the correct explanation of (A).
(A) is true but (R) is not true.
(A) is not true but (R) is true.
Both (A) and (R) are true and (R) is the correct explanation of (A).
Identify X and Y in the following reactions-
C.
i. On reduction in neutral media, using Zn dust and NH4Cl solution nitrobenzene gives phenyl hydroxylamine.
ii. While in alkaline medium, using Zn-NaOH, mononuclear intermediate products (nitrobenzene and phenylhydroxyl amine) interact to each other to give dinuclear product. Final product using Zn-NaOH is hydrazobenzene, which in a formed viz the
formation of azoxybenzene and azobenzene.
