Chemistry - What's in a Bond?
What's in a bond? If starch were not covalently bonded, would it still smell as sweet?
OK, probably not, considering it burns. And yes, probably about 98% of people did not catch my hopeless Shakespeare pun.
In this lab last week, our chemistry class investigated bonding, the force holding atoms together. As it turns out, we can determine covalently bonded (sharing of electrons) structures from ionically bonded (electro-magnetically attracted) structures by their melting points and conductivity in water!
Armed with our homemade bunsen burner (courtesy of Mr. Monroe - thanks!) and a multimeter, we put three compounds to the test.
The ionic compound (NaCl) conducted electricity in water and only melted at a high temperature. The covalent compounds did not conduct electricity and melted much sooner.
