324123 Primary amines can be distinguished from other amines by which of the following test?

1 Tollen's test
2 Schiff's test
3 Carbyl amine test
4 Fehling test
CHXII13:AMINES

324124 Nitration of aniline in strong acidic medium also gives m-nitroaniline because

1 In absence of substituents nitro group always goes to m-position.
2 In acidic (strong) medium aniline is present as anilinium ion.
3 In electrophilic substitution reactions amino group is meta directive.
4 Inspite of substituents nitro group always goes to only m-position.

324125 Read Assertion and Reason carefully to mark the correct option given below.
Assertion :
p-fluoroanilinium ion is more acidic than anilinium ion.
Reason :
Electron density in the N-H bond of p-fluoroanilinium ion decreases and release of a proton from p-fluoroanilinium ion is much easier than from anilinium ion.

1 Both Assertion and Reason are true and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.
3 Assertion is true but Reason is false.
4 Assertion is false but reason is true.

324126 Assertion :
Aniline hydrogen sulphate, on heating, forms p-aminosulphonic acid.
Reason :
The sulphonic acid group is electronwithdrawing.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
