The exactly answer is choice D.
Lewis dot structures space the structures which represent the valance electrons of an aspect forming a compound. The electron are stood for as the dots.
In a compound, the bonded electrons are stood for as a bond and lone pair of electrons are represented as dots.
Electronic configuration of Nitrogen:
Valence electron in nitrogen = 5
Electronic construction of hydrogen:
Valence electrons in hydrogen = 1
In the provided compound, link pairs space 2 which means number of electron bonded room 4.
Unbonded electrons left ~ above nitrogen will certainly be 3 and also this compound has actually an extra electron because of the negative charge existing on the compound. Hence, complete unbonded electrons current on this compound will be 4.
Therefore, the lewis dot structure will be choice D.
Both H and F atoms room bonded come the main carbon atom with solitary bonds and it"s in a crate form.
Explanation: Carbon has four valence electrons, H has actually one valence electron and F has actually seven valence electrons. All elements try to finish their nearest noble gas favor electron configuration.
Nearest noble gas come H is He and so it desires to complete two valence electrons. Rest of the elements try to complete eight electrons in their valence shell.
As H has one valence electron, it develops a single covalent shortcut to complete two electrons in the valence shell.
F has seven valence electrons and also it demands one much more to complete eight electrons in the valence shell and also so it additionally makes a solitary covalent bond.
Carbon has 4 valence electrons and also it requirements four an ext electrons to finish eight electrons to the valence shell.
So, in Lewis dot framework of the carbon atom is the main atom and two H and two F atoms room bonded come it with single covalent bonds.
The molecular geometry of the molecule is tetrahedral(in box form).
Lewis structure of the molecule is attached.
Both H and also F atoms space bonded come the central carbon atom with solitary bonds and also it"s in a box form.
Explanation: Carbon has four valence electrons, H has one valence electron and F has actually seven valence electrons. Every elements try to complete their nearest noble gas like electron configuration.
Nearest noble gas to H is He and also so it desires to finish two valence electrons. Remainder of the elements shot to finish eight electrons in your valence shell.
As H has one valence electron, it forms a solitary covalent bond to finish two electron in the valence shell.
F has seven valence electrons and it demands one much more to finish eight electron in the valence shell and also so it also makes a single covalent bond.
Carbon has 4 valence electrons and it needs four more electrons to finish eight electron to that valence shell.

So, in Lewis dot framework of the carbon atom is the central atom and two H and also two F atoms are bonded come it with single covalent bonds.
