Question

Identify the geometry about interior atoms in ch3nh2.

Answer 1

In CH3NH2, also known as methylamine, the central nitrogen (N) atom is bonded to three hydrogen (H) atoms and one methyl group (CH3). If there are 4 electron pairs around the central atom, the molecular geometry is tetrahedral.

1. Identify the total number of valence electrons for the molecule:

- Carbon (C) contributes 4 electrons (group 14).

- Hydrogen (H) contributes 1 electron each.

- Nitrogen (N) contributes 5 electrons (group 15).

So, the total number of valence electrons is 4 (C) + 3 (H) + 5 (N) = 12 electrons.

2. Determine the number of electron pairs around the central nitrogen atom. In this case, there are:

- 3 single bonds to hydrogen (3 electron pairs).

- 1 single bond to carbon (1 electron pair).

So, there are a total of 4 electron pairs around the central nitrogen atom.

3. Use the VSEPR theory to predict the geometry based on the number of electron pairs:

- If there are 4 electron pairs around the central atom, the molecular geometry is tetrahedral.

Therefore, the geometry around the interior nitrogen atom in CH3NH2 is tetrahedral.

Answer 2

Both the carbon and the nitrogen atoms in the compound are tetrahedral

Methylamine, or CH3NH3, contains an internal nitrogen (N) atom. The valence shell electron pair repulsion (VSEPR) theory can be used to ascertain the geometry surrounding this nitrogen atom. Four regions of electron density are suggested by the molecular formula to surround the nitrogen atom: one lone pair and three single bonds to hydrogen atoms.

The electron geometry of the interior nitrogen and carbon atom in CH3NH2 is tetrahedral.
