Question

What is the name of Si3N4

A) silicon nitride
B) trisilicon tetranitride

Answer 1

`\textrm {A) silicon nitride}`

Step-by-step 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.}`
