Make up the formulas of substances by name: a) 4-methylhexanol-2 b) 3-ethylphenol c) ethylmethyl ketone d) 3-methylpentanal

a) 4-methylhexanol-2 (we draw 6 carbon atoms, corresponds to hexane, at the second carbon atom – OH group, at 4 – methyl group, the compound belongs to the class of alcohols);

b) 3-ethylphenol (phenol – hydroxybenzene, at 3 carbon atoms, in the meta position, ethyl CH3-CH2 group);

c) ethylmethyl ketone (this is the name of butan-2-one according to the rational nomenclature, the carbonyl group C = O is drawn, the methyl and ethyl groups are drawn on both sides of it);

d) 3-methylpentanal (pentane – 5 carbon atoms, the ending al indicates that the compound belongs to aldehydes, which means that the carbonyl C = O group will be at the extreme carbon atom, from which the numbering of the entire chain will go. …
