: Tasks often involve writing structural formulas for isomers and naming them according to IUPAC rules.
One Hydrogen atom is replaced by one Halogen atom, releasing HClcap H cap C l Resources for Support g.e rudzitis f.g feldman 10 klass stranitsa 22 uprazhnenie
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
If you are working through these exercises, here is how to approach the most common types of tasks found in this section: :
Megaresheba provides systematic guidance for the basic level curriculum. One Hydrogen atom is replaced by one Halogen
: Balancing reactions for the combustion or substitution (halogenation) of methane and its homologs.
