On the C4 - Butane - branched molecule...is that written correctly?

Organic Structures, Isomers, Functional Groups

  • Hydrocarbon formulas: CnH2n+2 saturated; CnH2n has one double bond or one ring

  • Saturated hydrocarbons have isomers for n = 4 and above

  • Draw isomers for n = 5, 6 etc. – both saturated and unsaturated

  • Geometric isomers: different arrangements about double bonds

  • Optical isomers: non-identical with mirror image; opposite effects on plane-polarized light

  • Learn functional groups: OH – alcohol; COOH – carboxylic acid; COC - ether; COOC – ester; CO in aldehydes and ketones

  • Learn nitrogenous functional groups RNH amines; CONR amide as found in peptides and proteins
