What is the beta carbon atom?

Back (Answer)

Third carbon atom

Fourth carbon atom

#4
Front (Question)

Reaction of the amine group

Back (Answer)

Reacts with acids to make salts

#5
Front (Question)

Reaction of the carboxylic acid

Back (Answer)

React with aqueous alkalis to form salt and water Esterification with alcohols

#6
Front (Question)

Zwitterion

Back (Answer)

When the basic amine group can accept a proton from the carboxylic acid to form an ion with both a positive and negative charge

Isoelectric point

Back (Answer)

pH at which zwitterion is formed

#8
Front (Question)

Front (Question)

How are optical isomers drawn?

Back (Answer)

As mirror images to each other
