Okay, let's solve these organic chemistry reactions step by step.
Reaction 13:
CH3Br + NH3 → CH3NH2 + HBr
The reaction of methyl bromide (CH3Br) with ammonia (NH3) results in the formation of methylamine (CH3NH2) and hydrogen bromide (HBr). The ammonia acts as a nucleophile, attacking the carbon atom in methyl bromide and displacing the bromide ion.
Here's a more detailed view using the principle of nucleophilic substitution:
CH3Br + NH3 → CH3NH2 + HBr
Reaction 14:
(CH3CH2)2NH + CH3Br + NH3 → (CH3CH2)2N(CH3) + NH4Br
The reaction of diethylamine ((CH3CH2)2NH) with methyl bromide (CH3Br) in the presence of ammonia (NH3) results in the formation of diethylmethylamine ((CH3CH2)2N(CH3)) and ammonium bromide (NH4Br). Diethylamine reacts with methyl bromide to form a tertiary amine, and the ammonia acts as a base to neutralize the HBr formed, leading to ammonium bromide.
Here's a breakdown:
(CH3CH2)2NH + CH3Br + NH3 → (CH3CH2)2N(CH3) + NH4Br
Final Answer:
13) CH3Br + NH3 → CH3NH2 + HBr
14) (CH3CH2)2NH + CH3Br + NH3 → (CH3CH2)2N(CH3) + NH4Br
