What product is formed when benzene is treated with the following organic halide in the presence of alcl3?

Explanation:

This is an example of a Friedel-Crafts alkylation.

Since no organic halide is provided, we'll use an example of how benzene reacts with chloroethane, for instance.

Benzene is not reactive, therefore, we require a catalyst for such a reaction, typically either aluminum chloride or iron(III) chloride. It provides a pathway to add an alkyl chain to the benzene ring by removing the halogen present in the R-Cl molecule.

The mechanism is summarized by:

This is a so-called electrophilic substitution mechanism. To illustrate it with my example, I'm providing an image below.

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
