Marking chemistry IA highlight
"Without hydrogen bonding all natural, water based phenomena would cease to exist and the human race would go extinct, emphasising the importance of this molecular force."

A #microwave works great to demonstrate or explain #HydrogenBonding too

Not sure if this is well known or not but #ice will not heat up in a microwave. (The H bonds hold the H2O in the ice crystal lattice and prevent rotation/reorientation with the shifting dielectric field)
You need liquid or vapor water to heat up (and pass the heat on) in a microwave
