What is the molecular geometry about nitrogen in ch3nh2?
1 answer:
In Methyl Amine the Nitrogen atom is attached to two Hydrogen Atoms and one Methyl (CH₃-) group. From Lewis structure it is shown that the Nitrogen atom also contains a lone pair of electron.
So,
According to Valence Shell Electron Pair Repulsion (VSEPR) Theory, those central atoms which have four electron pairs and all of them are bonding electron pairs gives Tetrahedral Geometry.
Methylamine also contains four electron pairs, but out of four only three are bonding pair electrons and one lone pair electron. Now, due to presence of lone pair of electron (which has greater repulsion effect than bonding electron pair) the bond angle between H-N-H will decrease from 109° to 107° and results in the formation of <span>Trigonal Pyramidal geometry as shown below,</span>

Answer : We can produce 125.7 g of .
Explanation : The reaction will be
The molecular mass of is 64.1 g/mol
and molecular mass of is 34.1 g/mol
For every mole of we would need twice of
moles, so for every 3 moles of
we need 16 moles of
Now, we can calculate number of moles
2.61 X (3/16) = 0.49 moles
Here, the molecular mass of is 256.8 g
multiplying it with the number of 0.49 moles we get, 256.8 X 0.49 = 125.7 g of .
Hence, 125.7 g of will be produced.
