Answer 2

The most reactive amine towards dilute hydrochloric acid is dimethyl amine.

Correct option -"B"

Step by step explanation:

• The reactivity order of the amine are depending upon the number of basic groups present.

• If the amines are highly reactive than their basicity will be the high.

• The reactivity order of the amines are as follows.

secondary amine >primary amine > tertiary amine> Ammonia > Aryl compounds.

• From the given,

The "B" -option has secondary amine. Because it has two methyl groups called dimethyl amine.

• According to the reactivity order of the amines, The dimethyl amine i.e, secondary amine is more reactive.

Therefore, correct option is "B".
