In every form of hockey played on Earth, substitutes are free, unlimited and can take place at any time (except sometimes during certain plays in a game; for example, during a penalty corner in Field Hockey).
Substitution can occur in a great many different situations. Substitution usually occurs when someone is scheduled to teach for example and becomes sick.

Electrophilic substitution occurs in furan, thiophene, and pyrrole because these compounds have a lone pair of electrons on the heteroatom (oxygen, sulfur, or nitrogen), making them nucleophilic and reactive towards electrophiles. The aromaticity of these compounds is also maintained during the substitution reaction, making them favorable candidates for electrophilic substitution.
No. Immediately after the foul is committed.
The ortho position in benzene is significant in chemical reactivity because it is one of the positions where substitution reactions can occur. Substitution reactions at the ortho position can lead to the formation of different compounds with unique properties. This makes the ortho position important in understanding the reactivity of benzene and its derivatives.

Hockey players depend on the ice. They sway from side to side in a constant motion which causes friction to occur between their ice skates and the rink itself.
marginal rate of substitution
Yes, SN2 and E2 reactions can occur simultaneously in a reaction mixture, especially when both nucleophiles and strong bases are present. This can lead to a mixture of products with different substitution and elimination outcomes.
