Quiz - Amines and Derivatives | Amines and their Derivatives
Which of the following molecules is a secondary amine?
Which of the following statements is correct about ethylamine?
EtNH2 is immiscible with water
EtNH2 has a higher boiling point than EtOH
EtNH2 is a good electrophile
Hydrogen bond formation occurs between H2O and EtNH2
Amines have properties similar to alcohols and ethers. They can serve as nucleophile and participate in hydrogen bonding (high boiling point + soluble in water). However, oxygen is more electronegative than nitrogen ⇒ amines have weaker hydrogen bonding than alcohols and so lower boiling point
Which of the following statement about the reaction between 1-bromopropane and ammonia is incorrect?
The first step is a nucleophilic substitution
The reaction specifically gives a primary amine
The reaction initially gives propan-1-amine
One of the byproducts is NH4+
Which of the following statements about the reaction between pentanenitrile and LiAlH4 is correct?
The reaction is a reduction
The product is 1-butylamine
There is no significant change in carbon NMR
All of the above
Which of the following reagents is used for the reductive amination of an aldehyde?
