Draw it draw lewis dot structures for each hypothetical molecule shown below, using the correct number of valence electrons for
each atom. determine which molecule makes sense because each atom has a complete valence shell and each bond has the correct number of electrons. explain what makes the other molecules nonsensical, considering the num- ber of bonds each type of atom can make
1 answer:
The first molecule is a sensible molecule having complete octet of each atom such as C, H and O whereas the second molecule having hydrogen present between the aldehyde and methyl group and thus showing hydrogen is making bond with aldehyde and methyl as well which is not possible because hydrogen only having one electron in its octet due to which it can only form a single bond by sharing its valence electron.

Answer:
The correct answer is
B.
Explanation:
Enthalpy of reaction :
It is the amount of energy released/absorbed when one mole of the substance is formed from the reactant at a constant pressure.
The enthalpy of a reaction can be calculated using :
Please note that :
The carbon monoxide , CO should be taken as C triple bond O. Not C=O .
So , the bond energy =1072 is used
