10.1 Fundamentals of organic chemistry SL
• A homologous series is a series of compounds of the same family, with the same general formula, which differ from each other by a common structural unit.
• Structural formulas can be represented in full and condensed format.
• Structural isomers are compounds with the same molecular formula but different arrangements of atoms.
• Functional groups are the reactive parts of molecules.
• Saturated compounds contain single bonds only and unsaturated compounds contain double or triple bonds.
• Benzene is an aromatic, unsaturated hydrocarbon.
• Explanation of the trends in boiling points of members of a homologous
• Identification of different classes: alkanes, alkenes, alkynes, halogenoalkanes, alcohols, ethers, aldehydes, ketones, esters, carboxylic acids, amines, amides, nitriles and arenes.
• Identification of typical functional groups in molecules eg phenyl, hydroxyl, carbonyl, carboxyl, carboxamide, aldehyde, ester, ether, amine, nitrile, alkyl, alkenyl and alkynyl.
• Construction of 3-D models (real or virtual) of organic molecules.
• Application of IUPAC rules in the nomenclature of straight-chain and branched-chain isomers.
• Identification of primary, secondary and tertiary carbon atoms in halogenoalkanes and alcohols and primary, secondary and tertiary nitrogen atoms in amines.
• Discussion of the structure of benzene using physical and chemical evidence.

I envy whoever has you as their actual teacher

"you probably feel like dying" I laughed so hard, it was funny

[slimshady]

What gets me through watching this video - at least it's the last topic i will learn in IB chemistry 🤪 (we already covered topic 11 so)

“You probably feel like dying”
Me: yes, yes I do.
There’s so many different names my brain hurts.:(

Just wanted to point out there is a pretty easy way to remember the 2n+2, 2n and 2n-2 patterns if you just make a visual representation fo the structure. An alkane will have 2 hydrogens for every c plus 2 more for the outer carbons, which gives 2n+2. The double bond gets rid of the need for 2 extra hydrogens, hence 2n. And of course a triple bond gets rid of 2 more hydrogens, making it 2n-2

great video, thank you so much! btw at 9:45 can you tell me why the 5-methylhex-2-ene, the added alkyl group's position is counted from the opposite side the position of the double bond is counted, I mean why is it 5-methyl and not 2-methyl?

[s.i.d.]

at 16:16 wouldn't it be 2-ethoxy-2-dimethylpropane?

[okiedokie]

may I ask you where did you get the ppt? did you make it yourself?

[cocoriminton]

At 9:21, is it meant to be naming branched alkenes rather than alkanes?
