Answer : The correct option is, (B) no double bonds.
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'.
As we are given that the structure of the compound containing 1 carbon and 4 chlorine atoms.
Thus, the molecule is,
As we know that carbon has '4' valence electrons and chlorine has '7' valence electrons.
Therefore, the total number of valence electrons in = 4 + 4(7) = 32
According to Lewis-dot structure, there are 8 number of bonding electrons and 24 number of non-bonding electrons.
From the Lewis-dot structure we conclude that there are 4 single bonds are surrounding the central atom of this ion there is no double or triple bonds are present.
Hence, the correct option is, (B) no double bonds.
Answer: 437 g C6H6
Explanation: Solution attached:
1 mole of C6H6 is equal to its molar mass 78 g C6H6.
5.6 moles C6H6 x 78 g C6H6 / 1 mole C6H6
= 437 g C6H6
since the unit for the heat of fusion is kJ/mol, you're going to have to convert the grams into moles in order to cancel out the unit. After that, you can solve like normal.
