What is the name of Si3N4 A) silicon nitride B) trisilicon tetranitride

Answer 1

What is the name of Si3N4

A) silicon nitride .

Answer 2

Answer:

$\textrm {A) silicon nitride}$

Explanation:

$\textrm {The title of the compound}$  $\mathrm {Si_{3}N_{4} }$ $\textrm {is silcon nitride.}$

$\textrm {It cannot be called trisilicon tetranitride because a nitride group}\\\textrm {has 3 nitrogen atoms, and tetranitride would mean it has 4 times}\\\textrm {the number of atoms.}$

$\textrm {Furthermore, tri- and tetra- are prefixes used for substituent}\\\textrm {groups present in compounds. Here, since only both of them}\\\textrm {are present, it cannot be called so.}$
