For students needing step-by-step verification, several platforms provide detailed solutions and pedagogical advice:
The textbook "Chemistry, 10th Grade" by and F.G. Feldman is a staple in Russian secondary education, focusing on organic chemistry. Page 22 of this textbook typically contains exercises and problems related to the early chapters of the course, often specifically focusing on alkanes (saturated hydrocarbons) or the theory of chemical structure .

Depending on the edition (e.g., 1999, 2012, or 2019), the exercises on page 22 generally cover:
Identify the longest continuous carbon chain to determine the base name (e.g., pentane). Number the chain from the end closest to the branches. CnH2n+2+O2→CO2+H2Ocap C sub n cap H sub 2
: Tasks often involve writing structural formulas for isomers and naming them according to IUPAC rules.
: Calculating the mass or volume of reactants and products (e.g., finding the volume of CO₂ produced from burning a specific mass of propane). Solving Common Exercises Feldman is a staple in Russian secondary education,
