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:
c. Cr
Explanation:
The compound is containing ion.
If acid reacts with it, CO_2 evolves.
therefore, Cr would form a precipitate when added to an aqueous solution of this compound. Cr2CO3 is the precipitate.
