Arrange the following compounds in increasing order of their basicity:
$CH_3NH_2, (CH_3)_2NH, C_6H_5NH_2, (CH_3)_3N$

Which of the following compounds gives an even number of Hoffmann's exhaustive methylation and elimination cycles?

In the given reaction,what is the structure of the major product $X$?

What is the correct decreasing order of basic strength?

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$: Experimental reaction of $CH_{3}Cl$ with aniline and anhydrous $AlCl_{3}$ does not give $o-$ and $p-$methylaniline.
Reason $(R)$: The $-NH_{2}$ group of aniline becomes deactivating because of salt formation with anhydrous $AlCl_{3}$ and hence yields $m-$methylaniline as the product.
In the light of the above statements,choose the most appropriate answer from the options given below.

Which of the following statements is incorrect?
