Cyclohexasilane, Si 6 H 12, also known as CHS, is one such silicon precursor. It’s a liquid at room temperature, allowing for easier storage and handling, and it offers a moderate boiling point, 80 C at 15 torr. CHS has long been considered as the preeminent
Multipliive Valency-Based Descriptors for Silicon …
Wiener, in 1947, firstly introduced the concept of the topological index while working on a boiling point . In particular, Hosoya polynomial [ 7 ] plays an important role in the area of distance-based topological indices; we can find out Wiener index, hyper-Wiener index, and Tratch-stankevich-zefirove index by Hosoya polynomial [ 8 ].
Why do covalently-bonded compounds have low melting …
Original question: Why do covalent bonds have low melting and boiling points? They don’t. Check out the melting/boiling points of diamond, or crystalline silicon, for starters: those are covalently-bonded networks, analogous to the sort of extende
