IB Chemistry Topic 4.2 Covalent bonding

IB Chemistry Topic 4.2 Covalent bonding
How to determine if a compound is covalent or ionic (degree of covalent character), how polar the covalent bond is and if the molecule itself is polar. A look also into the strength of the covalent bond.

3:25 Polarity
5:26 Bond strengths

4.2. Covalent bonding SL
• A covalent bond is formed by the electrostatic attraction between a shared pair of electrons and the positively charged nuclei.
• Single, double and triple covalent bonds involve one, two and three shared pairs of electrons respectively.
• Bond length decreases and bond strength increases as the number of shared electrons increases.
• Bond polarity results from the difference in electronegativities of the bonded atoms.
• Deduction of the polar nature of a covalent bond from electronegativity values.

why do i study chemistry if this guy just handing out the cheat codes?

[MaccasAustralia]

Nice videos. Critical feedback; try not to block the tables and diagrams etc or like move your face to another area or not include it in that ortion of the video. This truly is helpful though

how are triple bonds harder to break? in many examples, triple and double bonds break easier than single ones, because it is easier to add an atom to them

I could not see the table at the end, pls try to have a better way to view the table

Come in my ss if I am going to pass ib chemistry

you said high melting and boiling points by mistake.
