Unformatted text preview: by___ Ka Charge is always____ Conserved in chemical reactions Rules of resonance 1. Connectivity is the same; only electron position can vary 2. Same number of electrons, same net charge 3. Same # of unpaired electrons 4. If the octet rule is broken for a 2 nd-row element, the structure does not contribute A strong acid will have a strong or weak bond? Weak bond electronegativity A weak acid is least electronegative, a stong acid is most electronegative, because the electronegative A will take electrons from H and HA will dissociate more easily Greater pKa=___bond Stronger bond pKa = ?-logKa Lowest heat of combustion is ____ The most stable isomer Prefix for 6 hexa Prefix for 5 penta Prefix for 4 tetra Prefix for 3 tri Prefix for 2 di 5 carbons pentane 4 carbons butane 3 carbons propane Seven carbons heptane 6 carbons hexane A stronger base has ____pKa Greater pKa...
