What is the exact chemical deduction according to Egyptian curriculum standards for: Markovnikov's Rule in Electrophilic Addition to Alkenes?
Hydrogen always attaches to the carbon with fewer hydrogen atoms
Markovnikov's rule applies exclusively to symmetrical alkynes like ethyne
Addition occurs with the halogen attaching to the terminal methyl group
When an asymmetric reagent (HX) adds to an asymmetric alkene, the positive hydrogen ion attaches to the double-bonded carbon with more hydrogen atoms, while the halide adds to the more substituted carbon
