The image of the strucure of this molecule shows nitrogen atoms in blue, hydrogen in grey, chlorine in green, and carbon shown conventionally by the origin of its four bonds near each end of the molecule. The chlorine which has substituted a hydrogen atom of an amino group - which is present as =N-Cl - is active as a germicide.«

Double Martini

A businessman enters a tavern, sits down at the bar, and orders a double martini on the rocks.
After he finishes the drink, he peeks inside his shirt pocket, then orders the bartender to prepare another double martini.
After he finishes that it, he again peeks inside his shirt pocket and orders the bartender to bring another double martini. The bartender says, "Look, buddy, I'll bring ya' martinis all night long - but you gotta tell me why you look inside your shirt pocket before you order a refill."
The customer replies, "I'm peeking at a photo of my wife.
When she starts to look good, I know it's time to go home."
