Question
Identify reagents that can be used to convert formaldehyde into trimethylamine.Select answer from the options below1) NaBH4 2) NH31) LiAlH4 2) NH3[H+], (CH3)2NH, NaBH3CN[H+], (CH3)2NH
Solution
The reagents that can be used to convert formaldehyde into trimethylamine are [H+], (CH3)2NH, NaBH3CN.
Here's the step-by-step process:
-
The reaction starts with the protonation of formaldehyde by a strong acid [H+]. This makes the carbonyl carbon more electrophilic and susceptible to nucleophilic attack.
-
The nucleophile, in this case, dimethylamine ((CH3)2NH), attacks the carbonyl carbon, forming a tetrahedral intermediate.
-
The intermediate loses a proton to form an imine.
-
The imine is then reduced by sodium cyanoborohydride (NaBH3CN) to form the final product, trimethylamine.
So, the correct answer is [H+], (CH3)2NH, NaBH3CN.
