In the following reaction the major product is:

Which of the following is a correct decreasing order of boiling points of the given isometric compounds:
Ethyldimethyl amine (I), n-butylamine (II), Diethylamine (III)

Which is the strongest acid amongst the following compounds?

Decreasing order of basicity is?
(i) $$CH_3NH_2$$
(ii) $$C_6H_5CH_2NH_2$$
(iii) $$p-CH_3O-C_6H_4-NH_2$$
(iv) $$m-CH_3O-C_6H_4-NH_2$$

I: $$CH_2 = CHCH_2NH_2,$$ II:$$ CH_3CH_2CH_2NH_2,$$III: $$CH\equiv CCH_2NH_2$$

The order of basicity in increasing order is:

Which of the following compound is strongest base?

What is the final product?

The order of basic strength the above compound is:

The decreasing order of boiling points of ethyldimethylamine, n- butylamine and diethylamine is n - Butylamine > Diethylamine > Ethyldimethylamine. This trend of the boiling point can be explained as:
