some of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes.

Of the molecules sicl4 and sii4, which has bonds that are more polar?
diamong [38]
The bonds in the SiCl₄ molecules will be more polar.

The polarity of bonds within a molecule depends on the difference in electronegativity of the atoms that are involved in the bond. Chlorine is a more electronegative atom than iodine. Therefore, the electrons in the Si-Cl bond will be more concentrated near the Cl, creating polarity in the bond. Iodine is not as electronegative, so it will not result in a very polarized Si-I bond

The electrophilic bromination or chlorination of benzene requires ______ along with the halogen.
Oksanka [162]

The electrophilic bromination or chlorination of benzene requires Lewis acid along with the halogen.

<h3>What is bromination of benzene?</h3>

The bromination or chlorination of benzene is an example of an electrophilic aromatic substitution reaction.

During the reaction, the bromine forms a sigma bond to the benzene ring, yielding an intermediate. Subsequently a  a proton is removed from the intermediate to form a substituted benzene ring.

This reaction is achieved with the help of Lewis acid as catalysts.

Thus, the electrophilic bromination or chlorination of benzene requires Lewis acid along with the halogen.
