1.	What is the name of the bond which is caused by changes in electron density?(a) Vander Waals force(b) H bond(c) Hydrophobic interaction(d) Electrostatic bondThe question was asked during an internship interview.Question is taken from Biopharmaceuticals topic in chapter Biopharmaceuticals of Drug Biotechnology
Answer» The correct choice is (a) Vander WAALS force To explain: Van der Waals forces are also known as London forces. They are weak interactions caused by MOMENTARY CHANGES in electron density in a molecule. They are the only attractive forces present in nonpolar COMPOUNDS. The surface area of a molecule determines the strength of the van der Waals interactions between MOLECULES.
