Question

how to remember chemical reactions ?

Answer 1

There's so many chemical reactions, it's simply not possible to memorize all of them. At high-school level chemistry, all you need to know is a few reactions, the basics, such as single displacement, double displacement, combustion, and maybe a few others. But most of them, all you're doing is combining +/-


For instance: \(AB + CD \rightarrow AD + BC\) which is basically the same thing as if you look at it like this: \((A^- B^+) + [C^-+D^+] \rightarrow [A^-D^+] + (B^+C^-)\)

Answer 2

However, this isn't always the case. As you move higher in chemistry, the reactions become more complex and aren't quite as intuitive. For instance: \(CH_3(CH_2)_2BrCH_3 + HI \rightarrow CH_3(CH_2)_2ICH_3 + HBr\)
\(\huge OR\)

Answer 3

try to understand.

Answer 4

Back to basics, try to relate reaction in terms of electronic configuration to understand chemical bonds, after that practice and practice. Revise every couple of days.
