Question

In a gas phase reaction, dimethylamine, (CH3)2NH, reacts with HCl to form [(CH3)2NH2]Cl. In the reaction, dimethylamine is acting as a

The answer is: Lewis base and Bronsterd-Lowry base. I wanted to know why this is? Maybe I am writing the equation wrong, but I am confused as to why it is not a acid since, I think, it's accepting electrons.

Answer 1

YOUR equation will be right the reason is due to the structute of dimethyleamine. We can see in the structure of dimethyleamine that there are two methyle groups attached to it and one loan pair is present on nitrogen and we know that methyle groups are electron donating group due to inductive effect, and there are two methyle groups which make the loan pair highly unstable and this loan pair tend to donate so it act as lewis base and on other hand there is a high cloud of electron over nitrogen which tend it to accept +ve charge proton like H+ so it is Bronsterd-Lowry base.
