The species which accepts the lone pair of an electron is called Lewis acid.

The species that donates the lone pair of an electron is called Lewis base.

$\mathrm{Ï€}$bonds also act as lewis bases because they share their electrons with lewis acids.

In this reaction$\mathrm{Ï€}$ bond of ethene attacks on data-custom-editor="chemistry" $\mathrm{HCI}$the molecule to form chloroethane. The reaction proceeds as follow;

The species which accepts the lone pair of an electron is called Lewis acid.

The species that donates the lone pair of an electron is called Lewis base.

$\mathrm{Ï€}$bonds also act as lewis bases because they share their electrons with lewis acids.

In these reaction$\mathrm{Ï€}$ bond of but-2-ene react with $\mathrm{HCI}$which result in the formation of 2-chlorobutane. The reaction mechanism is as follow;

The species which accepts the lone pair of an electron is called Lewis acid.

The species that donates the lone pair of an electron is called Lewis base.

$\mathrm{Ï€}$bonds also act as lewis bases because they share their electrons with lewis acids.

In this reaction $\mathrm{HCI}$add across the double bond which results in the formation of the following compound;
