Polar bond Memes

When chemists make dad jokes about wildlife... The fourth panel shows hydrogen fluoride (HF) followed by "bear" - giving us "polar bear." Get it? Because HF creates a polar covalent bond due to the electronegativity difference between hydrogen and fluorine, and polar bears are, well, polar! Chemistry students everywhere are groaning while their professors smirk smugly behind their coffee mugs. The kind of joke that makes you simultaneously appreciate and question your science education.
