What is the difference between penicillin G and penicillin V?

Oral penicillin G is no longer used because it is subject to degradation in the presence of stomach acid. Penicillin V and amoxicillin have chemical structures that enhance their stability in acidic environments and result in improved oral absorption (bioavailability).Why is penicillin G not given IV?
Penicillin G benzathine and penicillin G procaine injection should never be given intravenously (into a vein), because this may cause serious or life-threatening side effects or death.What is the difference between penicillin G benzathine and procaine?
