Re: Recognizing Amphoteric Compounds

You can look at the fact of whether it gains or loses a proton (the Brownsted/Lowry definition) or you can look at whether or not it loses/gains an electron pair (the Lewis definition). Also, amphoteric, you have to look at the fact if the compound acts like an acid and a base, so you use the browns...

Re: Electronegativity

wait i think nitrogen is actually more electronegative than carbon since it's closer to fluorine which is the most electronegative atom on the periodic table.

Re: pi vs sigma

ya a pi bond is weaker because it cant rotate the same way a sigma bond can.

Re: Weak Acid/Base vs. Strong

It's honestly easier to memorize the strong acids and bases so when you have to identify the acids and bases, it will be quicker to recognize which are strong or weak.

Re: lone pairs

Yes, lone pairs are taken into account for hybridization because they are an electron region so they're used for placing electrons in hybrid orbitals

Re: LDF

Yes, all molecules have LDFs. LDFS are dependent on the number of electrons in the molecule because the more electrons in the molecule, the stronger the temporary dipole force of the molecule is.
