"WebThe BDE for H 3 Si−F is 152 kcal/mol, almost 50% stronger than the H 3 C−F bond (110 kcal/mol). The BDE for F 3 Si−F is even larger, at 166 kcal/mol. One consequence to these data are that many reactions generate silicon fluorides, such as glass etching, deprotection in organic synthesis, and volcanic emissions. [18] " - Is hf diatomic
