How many hydrogen atoms are in each molecule of trisilylamine?
lord [1]

Answer:

  • <u>9</u>

Explanation:

The amine functional group is obtained by subsititution of one or more hydrogen atoms in the ammonia compound.

Ammonia is NH₃.

Then,

  • by substituting one hydrogen you obtain R - NH₂.

  • by substituting two hydrogens you obtain R' - NH - R''

  • by subsituting the three hydrogens you obtain:

                        R'''

                         |

                 R' -  N - R''

In this case, the three subsitutuents are silyl groups. The silyl group is derived form silane and is SiH₃. So, the tcompound <em>trisilylamine</em> is:

                    SiH₃

                      |

          SiH₃ -  N - SiH₃

Thus, you can count 3 hydrogen atoms for every silylgroup for a total of <u><em>9 hydrogen atoms in each molecule of trisilylamine.</em></u>
