VSEPR Theory - lone electron pair influence
Bond Angle Distortion: Lone pairs reduce bond angles between bonding pairs. For example, in a molecule like NH₃ (ammonia), the ideal tetrahedral angle of 109.5° is compressed to around 107° due to the presence of a lone pair on nitrogen....

Why Does Water Evaporate at Room Temperature?
Water evaporates at room temperature because the molecules at the top of the liquid have less intermolecular attraction than those within the bulk. When the top layer is exposed to sunlight, some molecules gain enough kinetic energy to...

Why Do Clothes Feel Stiff When Air Dried But Soft Coming From the Dryer?
The difference between air-drying and tumble-drying is that air-drying keeps the cellulose fibers from reforming their hydrogen bonds more effectively, which makes the towel feel a bit fluffy. Tumble drying, on the other hand, causes the...
