When to know when to use SINGLE-BOND, DOUBLE-BOND, or TRIPLE BOND for compounds?
I would guess this is just basic chemistry so just follow the octet rule and use the Lewis dot diagrams. The number of valence electrons on a single O is 6. If two O’s were to bond, then there should be a double bond present. A bond counts as two electrons and since it’s a double bond, it already counts as four electrons being shared. At this point each O would have four unshared electrons each. Since both of them share four electrons and have another four unshared, the system follows the octet rule. N has 5 valence electrons. If you use a double bond, the result would be four shared electrons and three unshared for each N. That would only sum up to seven and is obviously not following the octet rule. Hence, a triple bond is used. H has only 1 valence electron and since we’re bonding two H’s, that amounts to a total of two. We can’t have a double bond ’cause the H’s can’t share more than 1 electron each. That’s why only a single bond occurs. And, if you check the number of electrons ea
