What is the lewis structure for the anion -CH2CN?
2 answers:
Answer : The Lewis-dot structure of is shown below.
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is,
As we know that carbon has '4' valence electrons, hydrogen has '1' valence electron and nitrogen has '5' valence electrons.
Therefore, the total number of valence electrons in = 4 + 2(1) + 4 + 5 + 1 = 16
According to Lewis-dot structure, there are 12 number of bonding electrons and 4 number of non-bonding electrons.
In this molecule, (CN) is cyanide group in which carbon bonded to the nitrogen by triple bond.
Hence, the Lewis-dot structure of is shown below.

Energy(heat) required to raise the temperature of water : 418.6 J
<h3>Further explanation </h3>Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
Specific heat of water = 4.186 J/g*C.
∆T(raise the temperature) : 10° C
mass = 10 g
Heat required :
